Looks like you'll have to initialize pciide_softc manually. A good way
to handle this would probably be to write cardbuside_common_attach()
or somesuch -- all other IDE @ cardbus devices could benefit. You can
still use pciide_lookup_product() with cardbus, the ID on cardbus should
be the same as on PCI (ca_id from cardbus_attach_args).
