Are you leaving the display color setting at 16 bit instead of 24 or 32?

I had used a Radeon 9000 (not 9600) set to 16 bit color without problems, 
something might be different for you.
I couldn't guess if it's the video driver or POV causing the trouble, but if 
you are sure the video driver is up-to-date that would be about all you can 
do for it.

Seems a rare thing to hear about such graphics card problems where POV is 
concerned.
