Easy one: the problem was reported in the messages.

We have no I/O mapping for the device.  Yet it was activated anyway...

The real problem is broken code in the CardBus resource allocation
section.  The range above is 2^32-1 bytes, instead of 0x1000 bytes.

Since there was no I/O mapping, the device doesn't appear in I/O
space.  The "no device here" result is 0xffff to every operation.

Grrr, what a useless message.  It appears several times intermixed with
other activity.  It never appears with the problem device.
