I have had terrible trouble with an NV6800 card on my AMD64 machine and a 1600x1200 LCD display. I mostly had to use the vesa driver, becauase sometimes the nv driver would just fail to initialize the card properly, and it would be just black, or wrong frequencies/jumbled: it was a mess. Vesa worked, but generally didn't let me go beyond 1280x1024. When nv was (occasionally) working I had the firefox bug surface. I've commented about this on the lists (and on usenet) before, so I thought that I'd better also mention, for the record, that I have completely solved the problem by replacing that card with an inexpensive ATI card that the radionhd driver recognizes as "RV635" based. Should have done it long ago... Everything appears to work perfectly, now. Cheers, Andrew
