 120. More changes derived from NetBSD/sparc:
      - Enable openprom interface for NetBSD/sparc (Marc La France).
      - Add a generic SaveScreen() implementation for SBUS adapters that don't
        provide their own (Marc La France).
      - Beef up generic cursor handling for SBUS adapters (Marc La France).
      - Add a cleaned up version of Michael Lorenz's driver for SBUS Weitek
        P9100 adapters.
