Well, it depends how MI VGA driver is implemented.
(My patch just reset VGA into mode 3 to make MI VGA driver work.)
AFAIK current MI VGA only supports up to 80x50 characters
on 640x400 screen mode with 8x8 pixel font.
According to pcvt driver(*), maybe we have to handle chipset dependent
part to support 132 column mode (because genuine VGA doesn't
support 800x600), but I think it should be done by chipset dependent
drivers as Jason and Martin said before.
