Well, i have to say that I have solved my problem by purging setserial
and letting kernel assign the serial ports and their interrupts. Now all
of the modem functions are there without any further ado. I guess the
setserial and pcmcia-cs have some problems communicating to each other
what resources are available/taken.

Hope this helps someone,
