problems with PCcards on Latitude D830 w/FC7

[jhsnyder]

Thanks to everyone who responded to my question about alsa on the D830.. I booted
the FC7.92 live CD, and sound works there, so I'm not going to worry about alsa on
FC7 further, seeing that FC8 is days away.

However I have another problem with the D830 which occurs both with FC7 and the FC7.92
live CD:

When I insert a PCcard which presents a USB interface to the system, ACPI rejects the card and writes to the system log:

I've tried several Verizon and one Sprint EVDO modems, as well as a couple of USB2 hub-extenders
(which add two USB2 ports to the system via the pccard interface). None of these work.

The USB versions of the EVDO modems work just fine. (That is: hardware USB works, software-USB-
on-PCcard doesn't.)

PCcards which do not present a USB interface to the system work fine (eg ether).

These cards all work in Windows XP, so it's not a hardware failure in this laptop.

System information:
Running Fedora Core 7 on a Latitutde D830, all software up-to-date via yum and the
network repositories. Also tried this on FC7.92 live CD, same error.

Wouldn't think it would matter, but the Intel device is a 4965 wireless card.

There are 4G of memory on the laptop.

Thanks for any suggestions.. kernel boot paras which affect the way interrupts are routed, maybe?
