Debian 3.1r1 looks better than previous version, though the second
character from left at top row gets constantly overwritten when the
screen scrolls.

NetBSD 4.0 looks OK.

Also you didn't apply the linkage fix I sent completely since the
linker now complains:
  LINK  openbios-builtin.elf
libopenbios.a(console_common.o): warning: multiple common of `video'
libsparc32.a(openbios.o): warning: previous common is here
libopenbios.a(video_common.o): warning: multiple common of `video'
libsparc32.a(openbios.o): warning: previous common is here
libpackages.a(video.o): warning: multiple common of `video'
libsparc32.a(openbios.o): warning: previous common is here
  GEN   openbios-builtin.elf.syms

Otherwise the patches look fine.
