I'm having a similar problem (a PCI ethernet device that worked under
2.2.7 won't work under 3.0) and I think it might be due to the changes
in pci_map_port().  Under 2.2.7 there's some code in pci_map_port()
that apparently enables intermediate bridges, but I don't see the same
functionality in the pci_map_port in the PCI compatibility code.  I've
sent some mail to Stefan about this, but he's apparently swamped.  If
anyone else can take a look at the PCI code and confirm my diagnosis
and provide me a workaround or a patch, I'd really appreciate it.  It
may also be causing you a problem, too.

I'd patch it myself, but without a PCI spec, that code looks pretty
daunting...
