Do what we should have done a long time ago:

Browse Source 
o If the class is PCIC_BRIDGE, subclass is PCIS_BRIDGE_PCMCIA and
  programming interface is 0, assume that it is a generic PCMCIA PCI
  chip we can program.  I don't think there are any of these that
  we don't know about, but you never know.
o If the class is PCIC_BRIDGE, subclass is PCIS_BRIDGE_CARDBUS and
  programming interface is 0, assume that it is a YENTA cardbus bridge
  that we know how to cope with.  There are likely some cardbus bridges
  that haven't it made it in here yet.
