 121. Consolidate compatilibity definitions for OpenBSD/sparc and bump video

      - 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).

      - Add a cleaned up version of Michael Lorenz's driver for SBUS Weitek
        P9100 adapters.
 119. Another merge of NetBSD changes:
      - Support absolute mouse position events (Ty Sarna).
      - Fix bug that caused an entire batch of mouse events to be rejected
        when one of an unknown type was encountered (Ty Sarna).
      - Support horizontal scroll wheels (Iain Hibbert, #13821).
      - Don't error out on unknown wskbd types (Nathan J. Williams).
      - Add support for NetBSD/x86_64 (Frank van der Linden).
      - Update NetBSD section of Imake.cf.  Ditto for NetBSD.cf.  Note that
        the latter might temporarily cause build breakage
        (Marc La France).
