this is a great goal.

unfortunately, some of the machines i happen to have
have awful performance with the vesa driver.  in particular,
a scrolling window on my amd sb600 machine will essentially
lock up the machine.  you can't use the mouse to kill the
window.  :-(.  the nvidia driver (for different hardware
in the same machine) performs much better with a bargin
bin card.

also, is it possible to support resolutions greater than
1600x1200x16 with vesa?
