I programmed the SeaBIOS PCI code based on the suggestions I received
by other coreboot developers.  It scans at least bus 0, and it also
extends its search should it find any bridge or cardbus devices.  It
was my understanding that coreboot, filo, and libpayload were doing
something similar.

The current code is in src/pci.h in the foreachpci macro and in
src/pci.c in the pci_next() function.  If there is a better way to
scan, please let me know.

So, is it working now?
