I tried that driver...same problem, even with the modeline and IgnoreEDID lines removed.
I've never had an issue with 3D drivers in the past (same card, even), though this is the first time I've tried them with my 2001FP and the DVI interface. Just about every resolution looked like the above ones - the clock was too fast, h or vsync out of range.
Here's someone else having an issue. Is there something FC4-specific going on here?
