Just want to share a positive note, after months of fighting with ATI drivers (from ATI and Livna) I could not get GL support on my 9800 PRO in a dual head configuration on my FC4 x86_64. I just happened to give it another shot before buying an nVidia card. I downloaded the latest version 8.20.08 (12/08/05) from ATI and viola, finally 3D support. I lost the mouse scroll wheel when it wrote xorg.conf, I guess I'll figure that out when I diff the config files.
Just wanted to share. This was one of two remaining gripes. Now if I could find a decent mp3 juke box app . . .
