Bug Description
While attempting to get the fglrx dri working on my system, I found this in
Xorg.0.log:

(EE) fglrx(0): cannot init AGP

My system has a radeon 9700 mobile graphics card, and amd64 cpu. This happens
whether I use the 386, 686, or k7 kernel. I'm running the current Breezy
preview, with xorg-driver-fglrx 8.16.20 from the repositories.
Here is the output from "cat /proc/mtrr", in case it is helpful:
