SubjectRe: [PATCH] Fix for serial.c to work with Xircom Cardbus Ethernet+Modem

[snipped patch]

It seems something changed in 2.4.3-pre7 (against which I applied your
patch) so that it doesn't make a difference. On startup I now get this,
which I am CC:ing as per printk to serial-pci-info@lists.sourceforge.net

The card is a Xircom RBEM56G-100, despite what the card advertises.

(in case you wonder, cardmgr is from pcmcia_cs-3.1.25).


Thanks & ciao,
