Umm, I'm afraid it's much more difficult because
there are too many quirks to handle VGA mode registers.
Actually I spent many hours when I tried to implement
vga_subr.c:vga_reset() to get VGA mode 3 before consinit
on my arc Express5800/240 with the cirrus GD542x.
(though shark port could use OF commands to switch VGA mode)

Heh, yes, I agree it's right way to have all graphic chip
specific drivers ;-)

There was an Xfree86 3.x server for shark IGS written by DEC:
http://cvsweb.netbsd.org/bsdweb.cgi/xsrc/xc/programs/Xserver/hw/xfree86/vga256/drivers/igs/Attic/
so the only thing we have to do is porting it to XF4 IIUC,
but maybe I miss something.
