Ok, then add a couple printfs to the pci_read_vpd_reg line... one before
the WREG line, and another before the return... I have a feeling that
your card isn't setting the correct bit, as the printf you enabled w/
if 1 won't run unless it gets data from this function... If you're
hanging in this function, then I'll have to do something else... :( or
you could return the card/mobo as not PCI compliant... but I doubt
you'd want to do the last one..
