[PATCH] make Xircom cardbus modems work

[Bill Nottingham <notting@redhat.com>]

[-- Attachment #1: Type: text/plain, Size: 433 bytes --]

The attached allows serial.c to work with my Xircom cardbus
ethernet+modem combo card. It doesn't get autodetected, because
the serial driver explicitly doesn't recognize anything with
more than one iomem region (the Xircom modem has two.)
If the serial driver is linked in statically, the delay
on initialization is needed, else the UART will get detected
as a 16450 or not at all; I guess the card is just slow in
coming up.
