Interestingly enough, it did work as a module (no other changes to the system), 
so it must have somehow been related to that... 
Ksymoops showed the segfault to be occuring in prism2_open() somewhere
(sorry, I don't have the complete text anymore since of course the addresses
are different in the newly compiled kernel and I didn't save the old output
from ksymoops).

Anyway, it's working fine now and I can chat outside on my notebook  :)
Thanks for the help.
