Xircom cards are weird... the CIS (configuration data on the card) for the
various Ethernet/modem combo cards lists the standard sio port ranges, but
doesn't tell you that you need _another_ I/O port range for the Ethernet
part.  There's some cunning code in the driver to allocate that, but I'm
not convinced it works properly yet.  In your case the driver is failing
to allocate that port range, but I would have expected to see some more
debug statements telling us how it got to that point.

Anyway, you've one of many people seeing this problem, and I hope to make
some progress on it over the weekend.  All of my patches have been
committed, so it might be worthwhile upgrading to latest -CURRENT, turning
on the verbose debugging again, and seeing if you get any more output.
I'll be in touch as soon as I have anything for people to test.

Thanks for your patience...

	Scott
