First step towards making loadable modules independent of having

pccard in the kernel for those drivers with pccard attachments.  This
makes the compat layer a little larger by introducing some inlines,
but should almost make it possible to have independent attachments.
The pccard_match function are the only one left, which I will take
care of shortly.
