This should also be possible with my latest aty128fb code (almost finished).
I've got some cleanup and testing yet to do. I should be done in another
couple days to a week, time permitting.

Even it was so, it's only an Intel solution (possibly Alpha?).
There was some discussion on fbdev awhile back with the consensus being that
for optimal support, VGA BIOS should be ignored and the card [re]programmed
directly. From what I have been told, manufacturers are generally reluctant
to give out such information.
