Except for the subsystem's device ID. My C1VE shows for the cardbus
bridge:
	Class 0607: 1180:0475 (rev 80)
	Subsystem: 104d:80b1

I guess we'd better test for (class,vendor,dev,subsys vendor,ANY).

A much better solution would be using the DMI tables, but the 
implementation is not so immediate due to design problems (IMHO). See
my other post below.
