X crash with radeon driver - AGP broken?

Hi

Since I csup'd 7.0-BETA1, my computer reboots when I startx with the
(open source) radeon driver -- I also tried with a fresh -CURRENT with the
same result.

It's probably not the place for asking X related questions, however it
worked fine till then with a -CURRENT from mid-september (with the same
Xorg 7.3), and here's the last output I get before it reboots:

It seems to break in AGP related init (or just after that, I don't
know).

It works fine with VESA, so I wonder if I'm the only one with this
problem and if you have any idea about how to fix this or to investigate
further the problem. (I tried to rebuild everything that could possibly
be rebuilt).

My radeon is a 9600 Pro.

Any clue ?
