I agree it's _better_ . That's one of the reason why I made vga_reset()
be called from MD consinit(), not from MI VGA driver attachments.
My patch is just a hack, but I think it's still worth for some
obsolete machines. I think it's unlikely eventually someone will
write MI cirrus driver ;-p
The only changes I made in MI vga drivers are just adding some ops
to load default font from wsfonts. These ops could also be moved into
MD consinit(), but I left them in MI driver because they would be
useful even for old "genuine" VGA to replace default console font.

BTW, is there any reason why current vag_raster.c does not use MI rasops?
