Finally, a working driver!
Ever since I swapped my 7900GS out to a secondary system and put this x1900xt card into my primary, I've had a mountain of problems. Most of which centred around the fact that I run Fedora 7 64-bit, and the old ATI drivers hated it and/or me.
I'm happy (deliriously so) to say that 8.41 actually works. Full 3D support, proper resolution for my LCD, everything. A few days for my eyes to heal from the stretched text and images I've been dealing with, and all will be well.
It surely is reassuring to see at least some positives experiences!
