If I understand what your trying to get at you could parse through
/proc/ioports to figure it out. Do you need the ioports parameter? The
driver I'm using doesn't seem to care. With this line in my
/etc/modules.conf:
  post-install ni_pcimio
PATH=/sbin:/usr/sbin:/usr/local/sbin:$PATH;comedi_config /dev/comedi0
ni_pcimio

Anything that uses a device linked to comedi automatically loads drivers.
You also run a modprobe from within the program to do a similar thing. Did
that answer the question?
