Looks fine.  However, long term I've no idea what to do about this because
I don't remember the reasoning behind it.  So to change it risks breakage
of one sort or another.

It might have been something to do with the Mobility Cardbus docking
station, which adds a pair of P2P bridges onto the PCI chain downstream
of the Cardbus controller, and then a full PCI bus containing USB, VGA,
and other peripherals.

This _once_ used to work with Linux but I suspect as a result of "fixing"
other issues its now utterly broken.

In any case, that docking station isn't ARM specific in any way; merely
a toy Alan Cox sent me.  When I gave up my PCMCIA maintainership, I gave
up trying to keep it supported by Linux.
