imp 9f319f679b Additional enhancments to allow IBM Etherjet cards to be probed,
attached and ifconfigable.  The card doesn't interrupt yet.

Also, move towards bus space by introducing new macros/inline
functions which make such a move much easier than before.

These inline functions are setup now to work around an IBM EtherJet
pccard cardbus bridge incompatibility.  The card works in 8 bit mode,
but not in 16-bit mode when it is connected to a cardbus bridge for
reasons unknown.  The Linux driver also has a similar workaround in
it.

Future work will include making the above workaround runtime
conditional rather than compile time conditional, as well as fixing
the interrupts in pccards and converting it to bus space.
