Update:
It seems there is no bug at all.
I just downloaded the latest daily live CD (Kernel 2.6.26-5) and retested my
WLAN adapter on the PC of my house-mate. Well, i couldn't reproduce the error
on his PC.
Out of curiosity, i booted my pc with the live CD. Again, no OOPS occurred.
So my hard disk installation must have gotten corrupted somehow.
It didn't took me long to find a possible cause.

I ran memtest afterwards. (From the live CD, to be sure)
It crashes repeatedly after ~58000 errors in test #2 "Moving Inversions, ones &
zeros" regardless which of my 2 memory modules I've inserted.
I suspect a hardware error in the memory controller.
