Then, does your dmesg output show anything interesting? Like error messages or oopses?
Ok, I adapted my lunch schedule a bit and got the dmesg output (without
ChipID this time...). Long story short: yes, something causes an oops:
----------------------------------snip!----------------------------------
[fglrx] AGP detected, AgpState = 0x1f000203 (hardware caps of chipset)
Unable to handle kernel NULL pointer dereference at virtual address 0000000c
printing eip:
e09e62b8
*pde = 18a84067
*pte = 00000000
Oops: 0002 [#1]
