Ok...

Cards like ethernet/modem combos typically have 2 functions (in the PCMCIA
sense, much like multi-function PCI cards).  Each function will have its
own i/o port range, etc.

Unforunately, not a quick one... see below... More research is needed,
here, I think...

Note that your combo card seems to only present one PCMCIA function,
that being the modem.

It would be interesting to know about the experiences of people with
this card under FreeBSD's PAO stuff and/or Linux.  Perhaps they can
provide a crucial hint as to how to get this card to work... I have
the FreeBSD PAO stuff handy which I can peek at today, but the last
time I checked it (i.e. to grab the SMC91cxx driver in the first place),
it only grok'd the Megahertz card.
