Slow X on x86_64



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.
