Some clues. It is definitely not a problema of the hostap_pci driver,
but of the Mandrake enterprise kernel (quite possibly in the HIGHMEM
support).
I tried to use orinoco_pci, with exactly the same Oops. Later, I noticed
that I had removed usb-uhci (thinking about interruption problems) and
when I modprobe'd it it gave the same oops.
Being already suspicious about HIGHMEM, I tried the smp kernel (fairly
similar to the enterprise, but without HIGHMEM support). Then it worked
perfectly...
I'm losing about 100K RAM + all the swap, until they fix it. I'm trying
to report it @mandrake (I hate bugzilla!!!), but this post is for Google
to take care of the problem ;-)

P.S.) Jouni, keep on with your excelent job.
