One _minor_ nit ... while that's true about CardBus, all CardBus chipsets
I've seen _also_ support PCMCIA cards.  99% of them also support the 82365
register set, so the mostly "just work".

Doing a PCIC PCI attachment is relatively easy.  Doing a CardBus attachment
is harder.  I've looked at what needs to be done for the latter, but I
have not yet written any code (it's on the list, but it's a long list and
it's waaaayy down on the list :-/ ).
