I have a problem with a USB/Firewire card.  This is with
current-20031213.  The card is an USB 2.0 chip and an fwohci behind a
PCI-PCI bridge.  The kernel probes the bridge, but sees no devices
attached to the PCI bus behind the bridge.

I see dmesg where someone else has what looks like the same card
working in a different alpha:

Here's the boot messages (search for ^pci1):
