Thomas;
I don't know why, but you could try these other values to see what
works (looks like vga=773 would give you the same resolution but fewer
colors):
+ | 640x480 800x600 1024x768 1280x1024

+256 | 769 771 773 775

+16M | 786 789 792 795
I've actually tried all the way down to 769 with the same results. It's
doing it on both FC6 and RHEL5. It worked fine on the same machines
with FC5 and RHEL 4.
Very weird.
