I get the same oops with a 3com 3CRWE62092B pcmcia wireless card when inserting it (with 2.6.6, 2.6.5 works fine).
It might be related to this thread: http://lkml.org/lkml/2004/4/23/4 . I'm not really sure...
Please, let me know if I can provide any additional information to help.
This is the oops I get:
