Once again a pci_get_device conversation isn't all that helpfull at all.
fortunately in this case I've done a patch to convert this driver to
proper pci probing in 2004, and I've attached the forward-ported version
below now that we've actually found some testers that weren't locatable
back then..
This doesn't change much outside the initialization and irq code, so
any additional de-crappyfication will hopefully apply ontop.
