pccard recognition, irqs, and winmodems

I posted a couple of days ago regarding a couple of questions about
recognizing a winmodem, etc.  HAving poked around with windows and
a couple of other things, I think I have narrowed down my problems
to a couple of questions.

The basics:  Laptop is a Thinkpad T21 running 4.6-Stable as of
6/19 (roughly).

First, why is it that no matter what configuration setting I use 
in pccard.conf, the device inserted (both an orinoco wifi card and
this winmodem) insists on taking over IRQ 11.  The irq line in the 
pccard.conf file lists IRQ 3 5 9 10, for instance.  11 is not present,
yet it is acquired.  I tried using pccardd manualling with the -i,
and -I flags, still it grabbed 11.

Second, how exactly are pccards detected?  In other words, should 
the modem be showing up in a scan using pciconf -lv?  I can provide the
output, but the card does not show.  However, when the modem is inserted,
pccardd recognizes, and starts the initialization that I configured
in pccard.conf.

Last, how does ltmdm determine the type of modem loaded?  Under windows,
the modem is recognized as a winmodem and running happily using the 8.22
version of the driver from agere, prior to today it was running 5.87,
I believe.

I think the first two issues may be holding up the modem from working
and being recognized.  Is there any sort of information I can provde?
The dumpcis of the card?  pciconf output?

Note, that the only entry shown with dmeg is what is reported by 
pccardd and is:

wder# pccard: card inserted, slot 0

Thoughts, comments?
