I had one running on Gentoo last year, before the motherboard on an
800 MHz Athlon Slot-A died.  X ran fine.

Have you tried just using - vesa?  Or vga?  It should work.  Turning on everything 
is always a sure way to break a kernel.

Generally, it's because the gfx card can't refresh from it's internal memory fast enough.
As I recall, the Mystique had an optional memory module, which I have on mine.  Perhaps
its just that your trying to use too high a resolution and hitting the cards performance
limits?

With due respect, save up your pennies and get a current Gfx card.  Should be around
US$42.   Sure, that's a months wages in some parts of the world.  But still - throwing a massively
powerful processor in a system with a dead-end Gfx card is kind of wasteful, unless you're making
this thing into a server.
