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)

There was an Xfree86 3.x server for shark IGS written by DEC:
so the only thing we have to do is porting it to XF4 IIUC,
but maybe I miss something.
