I imagine that most pentiums nowadays come with gfx cards with at least
this? But how about VESA support? I know I had to get Scitech Display Doctor
for mine (Diamond FireGL with Permidia2). Is there any other way of getting
640x480x16 in Allegro?

This is good news, I wrote a quick demo of my game, and it runs at 60fps,
but I have programmed it really badly, just so I could see what it looked at
(it redraws the whole screen each time... hey it was quick and easy!). For
640x480x16, which of the animation methods is best?

Hmm.. I don't like palette stuff, I think I'll try and stick with 16+bit
from now on.
