 239. Add ACPI Hotkey switching support to the i810 driver (Alan Hourihane).
 238. Add 945GM support to the i810 driver (Alan Hourihane).
 237. Support 1920x1088 for HDTV movies in the i810 driver using a new option
      called LinearAlloc to add more memory for video overlay (Alan Hourihane).

 217. A rework of the way extension support is built into servers to allow for
      servers with different sets of extensions in the same build.  This starts
      with an idea introduced in David Dawes's TinyX work, and extends it to
      also apply to the Xprt, Xnest, Xvfb, Xdmx and Xsun* servers.  The changes
      include:
      - Add, as a comment, a definition for what makes an extension pervasive.
      - TOGCUP is not a pervasive extension, but XSYNC, BIGREQS and XRES are.
      - Consolidate #define's for the Xv, XvMC and XRES extensions.
      - Flip, in favour of the majority case, MITSHM's default decision WRT
        whether or not a framebuffer stores pixmap data in the server's virtual
        address space.  MI is now independent of MITSHM and MITSHM is no longer
        a pervasive extension.
      - Add a DIX helper to determine whether Xinerama is active and use it
        instead of #ifdef'ed code in all loadable modules.  Re-implement, as
        a screen wrapper, Xinerama's PaintWindow*() hacks.  Move down to DIX
        Xinerama's only MI hook.  Both MI and loadable module objects are now
        independent of Xinerama.
      - Add more XCSECURITY-related DIX helpers.  Loadable module objects that
        provide their own extensions (e.g. apm) are now independent of the core
        binary's support for XCSECURITY.
      - Extend DBE to allow for front and back buffer revalidations (to be used
        in future changes to restore the only existing example of DBE hardware
        acceleration after converting the sunffb driver to fb, XAA & Render).
        This is the change that chronologically started all this.
      - Separate Xv and XvMC extensions more cleanly.
      - Move Xserver/*/tiny directories under Xserver/hw/tinyx.
      - Fix !PrintOnlyServer builds.
      - Clean up Xserver/Imakefile.
      - Remove remaining traces of Xdec* servers.
      - Fix parallel make bug in Xserver/Imakefile caused by unintentional
        symbol re-use.
      - Accomodate XWin more cleanly by not "skipping" over Xserver/hw.
      - Remove all extension stub code (no longer needed).
      `make World` is required to correctly build these changes.  In fact, I
      recommend staring from a fresh checkout.  These changes are bundled as
      one commit due to module versioning considerations.  (Marc La France)

 161. Implement a major #include rework throughout the tree.  Also enforce it
      for all non-external builds (i.e. in-tree & SDK)  (Marc La France).
 160. Rework the building of hw/xfree86/parser to be more in line with the
      building of other server subdirectories (such as common/)
      (Marc La France).
 159. ANSIfy /xc/lib/font/builtins/, and fix warnings, whitespace & formatting
      (Marc La France).

Notes:
 - `make World` highly recommended ;-)
 - This will be further tested in the next few days.

  87. Fix Xvideo when operating in one line mode and video is pushed off
      the top of the screen. Also some fixes for Xvideo skew in certain
      resolutions in the i830 driver (Alan Hourihane).

missed a hunk

  66. Fix some offset, pitch and overlay scaler size problems with
      the video overlay. Solves various spontaneous lockups in the i830
      driver (Alan Hourihane).

  54. Add Intel(R) i945G support to the i830 driver (Tungsten Graphics).

 348. Fix an off by one error when scaling which caused occasional
      overlay color lines at the far right and bottom of the window for
      i830 chips (Alan Hourihane).

 324. Fix unaligned YV12 videos that caused skew when playing in the i830
      driver (Alan Hourihane).

 323. Fix pixmap cache corruption when Xv was in use due to a memory
      allocator calculation problem (Alan Hourihane).

 262. Add Intel i915GM support, also....
      - PanelID identification
      - DRI suspend/resume support
      - Detection of monitor changes on VT switches
      - Support custom video modes if available in the Video BIOS
      - 3D enhancements
      (Tungsten Graphics, Alan Hourihane & Keith Whitwell)

 131. Intel driver updates to support:-
       - i915 latest generation hardware
       - Dual Head & Clone support for i915, i855 and i830 chipsets.
       - ARGB cursor support for all Intel chipsets (requires agpgart updates)
       - Mobile lid status checking
       - Fix XVideo when high resolutions are used on LFP's

Remove comment that no longer applies.

  90. Fix flickering during XVideo's on i830's (Marc La France).

  40. Address Xv segfaults with Option "XaaNoSolidFillRect" by reducing output
      driver dependence on xaalocal.h (Marc La France).

 573. Rework REGION_* macros to eliminate NEED_SCREEN_REGIONS build failures
      (Marc La France).

 NOTE:  This might cause build failures in darwin, xwin, sunLynx and kdrive
        DDXen.
