What do you think? This is what the PCI Vendor/Device IDs are for. It's a shame that Broadcom apparently screwed up and used the same IDs in two different devices. At least, I *assume* they're different. I can't really tell what the bdc_pci driver does, so it's conceivable that it's using the same device in a different way than you are. If they really are different devices, using the class code sounds like a reasonable way to differentiate them.
