This is the message I need.  It looks like the kernel doesn't think you have 
PCI at all.  Hmm, it seems that you have a buggy BIOS or some such.  The high 
bit of 0xcf8 is always supposed to be clear I believe.  I'll have to wait 
until next week when I can get to my PCI book.  You can try forcing the check 
for CONF1 to succeed in sys/i386/pci/pci_cfgreg.c.
