Full dmesg output

Description of problem: 
When X is started, the fglrx module is loaded but crashes about immediately. Oddly enough, the X server does start and seem to work properly, even when starting applications (like wine games). Even the graphics are fine.

As soon as the application is closed and another X application is started, the system locks up. Sometimes the Caps-Lock keyboard light blinks and the PC reboots soon afterwards, meaning some kind of kernel panic occurred.

I have trouble debugging, because this error occurs in a livecd environment and the (fullscreen) X server prevents me from reaching the console after the panic.

Just after X is started the following error message appears in dmesg:

I also tried to compile the 12.4 driver directly from the AMD site, but this caused some compile errors:
/lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:5812:28: error: 'TS_USEDFPU' undeclared (first use in this function)
It compiles after applying this patch: http://phoronix.com/forums/showthread.php?68922-Patch-to-compile-fgrlx-module-on-Linux-3-3-rc4-with-x86-32-bit-arch
Sadly it still crashes afterwards.

Hardware:
Intel Core 2 Quad Q8400 @
6GB Kingston ValueRAM
Asus P5K/SE
ATI Radeon HD 4770

Steps to reproduce:
1. Build fglrx module for x86 kernel 3.2.12
2. startx

Actual result: 
Module crash

Expected result: 
No crash
