I think it's the serial driver stomping on the ATI's 8514-compatible
ports at 0x3e8. I have a Gateway 4DX-66V system with the ATI Graphics
Ultra Pro. Sometimes the display wouldn't be bothered at all,
sometimes it would turn yellow, once or twice it turned green, and
once it apparently changed to black on black :)
I changed the serial driver to not look for com3 and com4 anymore, and
I haven't seen the problem in the two or three boots since then. I'm
not saying it's gone, though. This is a very obvious edit to the
tables for serial ports in the driver.
Another way to get around it may be to use the card's INSTALL program
to configure it as monochrome, green VGA. I didn't see this problem
until I switched it back to booting in color VGA.
A comment for Linus and Ted Ts'o: in any case, some of us with
8514-compatible cards would feel much better with a config option to
turn com3 and com4 off in the serial driver.
