I've tried changing the s->io_offset = 0xf000 just to see if I get any reactions. The result is that now orinoco_cs segfaults, which it more or less should. 
Correct s->io_offset gives :
Segfault in hostap_cs

Bad s->io_offset gives :
Segfault in orinoco_cs
Segfault in hostap_cs

So basicly, the segfault in hostap_cs is not dependant on my io_offset at all.. :(
