Again, cardbus != pcmcia.
Cardbus is really a very PCI-like bus and so you'd need an if_wi_cardbus,
which would look a lot more like if_wi_pci than if_wi_pcmcia. 16-bit PCM-
CIA is much more ISA-like, on the other hard.
Pretty much the only thing the two share is a form factor for the physical
devices (even the connector is slightly different on cardbus devices, as a
result you cannot AFAIR put a Cardbus card into a 16-bit-only PCMCIA slot).
