Might it be the offscreen compositing stuff somehow? If there is
something like this floating around in /etc/X11/xorg.conf
Section "Extensions"
Option "Composite" "Enable"
EndSection
try setting it to Disable and restart X.
Looks like it is a xorg bug such that it does not set MTRR reducing AGP
performance by 2X:

Explains why I am seeing this recently too as xorg 7.0 was installed
late August. Fixed in xorg 7.1
I submitted a bug to redhat

After manually setting /proc/mtrr, xorg cpu usage has dropped from 70%
to 20%.
