2409. Updates to s3virge driver to get it working under Linux/Alpha
      (#2586, Matt Grossman).
2408. Fix getline() clash (#2585, Alan Hourihane).
2407. Have the s3virge driver use the new XAA rop helper functions (#2584,
      Mark Vojkovich).
2406. Add code to SuperProbe to detect the S3 Trio3D and Savage3D
      (2583, Eric Molitor).
2405. Add some XAA helper functions that drivers can call for help
      converting X rops into MS rops (#2582, Mark Vojkovich).
2404. Resync the overlay support in the glint driver (#2580, 2581,
      Mark Vojkovich).
2403. Add support for changing the overlay color key to the MGA driver
      (#2579, Mark Vojkovich).
2402. Preallocate the color key in the default colormap and set it to
      something already in the default man (black) so that AllocColor will
      never allocate it (#2578, Mark Vojkovich).
2401. Use the color key field in the ScrnInfoRec for the overlay layers
      (#2578, Mark Vojkovich).
2400. Preliminary loader support for Linux/PPC ELF objects (#2577 (2570),
      Stuart Anderson).
2399. Fix some XAA offscreen pixmap problmes (#2576, Mark Vojkovich).
2398. DGA fixes.  Old apps should now run with the new driver interface,
      and event handling should work better than before (#2575,
      Mark Vojkovich).
2397. Fix most remaining signed/unsigned and prototype warnings in the
      following directories: lib/Xaw, lib/Xmu, programs/xclipboard,
      programs/xconsole, programs/xmag, and programs/xvidtune (#2574,
      Thomas Dickey).
2396. Restore the interface of XmuConvertStandardSelection() to use
      XPointer rather than XtPointer (#2574, Thomas Dickey).
2395. Fix an malloc size bug in libICE (#2572, Christopher Sekiya).
2394. Make MIT-SHM resource types non-static so that other extensions
      (like Xv) can access client shared memory segments (#2571,
      Mark Vojkovich).
2393. First cut at altering the C&T user docs for 4.0 (#2569, David Bateman).
2392. Fix a C&T problem affecting the colourmap setup for 1bpp modes, and some
      other minor C&T driver fixes (#2569, David Bateman).
2391. Fix an buffer overflow in os/connection.c (#2568, Gerd Knorr).
2390. Add support for Modes sections and the UseModes keyword for Monitor
      sections to the parser (the data isn't used yet) (#2564, Dirk Hohndel).
2389. Fix xfree86.cf for Alpha (#2567, Dirk Hohndel).
2388. Fix XAAFillPolygonStippled to obey the flag NO_TRANSPARENCY in
      Mono8x8PatternFill (#2566, Xavier Ducoin).
2387. Only allow the shadowfb layer in the C&T driver when linear addressing
      is enabled (#2565 (2561), David Bateman).
2386. Fix some problems with the xf8_16bpp layer, and allow it to work
      with depth 15 as well as 16 (#2565 (2561, 2562), David Bateman).
2385. Implement TrueColor with PseudoColor Overlays (8+16) for the
      C&T driver for HiQV chipsets (#2565 (2561), David Bateman).
2384. Add a -quiet option to xgamma (#2565 (2561), David Bateman).
2383. Add TrueColor Gamma Correction for C&T HiQV chipsets (#2565 (2561),
      David Bateman).
2382. Fix Permedia 2 HW cursor lockup (#2563, Alan Hourihane).
2381. Initial XAA support for SiS530 and SiS620 (#2560, Xavier Ducoin).
2380. Add SuperProbe for SiS (#2559, Xavier Ducoin).
2379. Fix the InstalMultipleMan and InstallMultipleManSuffix rules for
      NetBSD and OpenBSD (#2558 (2557), Matthieu Herrb).
2378. Add Cards entry for Number Nine FX Reality 772 (#2556, Harald Koenig).
2377. Make XF86Setup build again (not fully functional yet) (#2555, Joe Moss).
