Output of dmesg without loading the module.


i am using Arch Linux with with the following kernels:
- kernel26-drm-radeon-testing 20110605-1
- kernel26
- kernel26-git 20110625-1

with my new ATI card (http://be.msi.com/product/vga/R6870-Hawk.html) i get a
complete system freeze (no SysRq Keys) after loading the radeon module. Except
i don't plug in a monitor. I already tried all three kernel versions: no

I have no problems if i use my internal radeon card (Radeon HD 3300).

Sadly i cannot find any advices in the kernel.log file.
So, i blacklisted the module and disabled gdm to get a terminal. The output of
dmesg is attached.
Then i plugged of the monitor and logged in (ssh). After that i loaded the
radeon module (see the attached output). It doesn't crash but i cannot see
anything on the monitor.
Now i started gdm and my system freezed (Xorg.1.log).

Any ideas? 
How can i provide more information?
