This might be OK -- the CardBus code maps the card CIS and loads the
driver before it finishes allocating the resources.  The code really
should finish mapping the card's resources before notifying the driver,
but David Hinds considers it my problem to work-around.

That's the PCI bus number for the CardBus controller.  This is a set by
the Linux PCMCIA code.

This looks OK.

First message, not really a problem yet.

OK, the PCI device mappings have been set up.  Good.

Good so far.

The card should now be working.
