I'm having a problem with an install of FC3 on an Opteron machine. The X performance is deadly slow; glxgears gives me less than 53 FPS. On a similarly x86 32-bit machine I'm getting well over 500 FPS. It's the same with both a Matrox G550 and an ATI Radeon 9200 card.
Seems to be a problem with drm and dri initialization.
Anyone else seeing this?
I've added to a bugzilla bug that seems to be on target. There are
errors and xorg.conf snippets there. Interestingly, it seems that it
isn't x86_64 specific.

Relevant log entries below.
I note that I have no /dev/dri directory. Created one, but it's gone on reboot. My 32-bit machine has these entries in dmesg, but the 64-bit machine does not:
