Is there any reason why a host bridge has to be matched against a list
of product and vendor ID's rather than just trusting the devices bridge
subclass code (which in this case would be PCI_SUBCLASS_BRIDGE_ISA)?

For that matter, is there any reason why any of the pci bridge code
has to match an IC's pid and vid against a list of known ID's?  Doing
things in the existing fashion seems like a losing battle as it will
be almost impossible to keep the match functions in up to date with
the ever growing number of PCI-to-whatever bridges.
