True, and too bad if any int's are added, I agree with Linus' original
comment that "we don't need no stinking BIOS...", but I agree that
reverse engineering these complex VGA chips is no easy task. However, I
am going to continue to do it as I have time. I don't know if there is
a good argument for this other than religious convictions. I seem to
get a certain amount of self satisfaction out of booting linux without
ever going into 16-bit mode, save the first instruction or two. And it
is disconcerting to see that linux is starting to use BIOS calls in some
places, like power management stuff (AFAIR).
