PCMCIA card conflict with PS/2 Keyboard

[meissenation]

Background information:
I purchased a kiosk awhile ago and started working on it to put it in
my car. It's basically a celeron 400mhz laptop in a heavy zink case
with a 10.5" touch screen. It has a USB 1.0 plug, a laptop PS2 plug (I
have to use a ps2 splitter cable for keyboard and mouse), and two
PCMCIA slots. Operating system is Windows 98.

For this to work in my car and have the features I need, I purchased a
linksys wcp11 wireless-b PCMCIA card, and a buslink USB 2.0 cardbus
for notebooks.
--------------------

The problem:
A: If I have the wireless-b card plugged in with a keyboard connected
through the ps2 splitter, both work perfectly fine.
B: If I have the USB cardbus plugged in with the wireless-b card, the
computer freezes.
C: If I have the USB cardbus plugged in with the keyboard, the
computer freezes.

Sometimes unplugging the cardbus will allow the computer to unlock and
work again, but for the most part it just locks up, the touch screen
stops responding, and the computer sits and no activity is apparent
from internals.

My dad said it was a possible IRQ conflict, but when he looked at it
for a few minutes, he said that it *looked* like everything was ok,
but he wasn't possitive. So, below is the list of IRQ's exactly as it
appears.

If anyone needs more information to figure this out, I'll give
whatever information I can, I'm desperate to get this working so I can
get my project finished.

IRQs:
00 System timer
01 Standard 101/102-Key or Microsoft Natural Keyboard
02 Programmable interrupt controller
04 Communication Port (COM1)
05 ESS Solo-1 PCI AudioDrive
05 Texas Instruments PCI-1225 Cardbus Controller
05 IRQ Holder for PCI Steering
06 Standard Floppy Disk Controller
07 ECP Printer Port (LPT1)
08 System CMOS/real time clock
10 Bt879 Fusion Capture Device - Audio Section
10 Bt879 Fusion Capture Device - Video Section
10 Texas Instruments PCI-1225 Cardbus Controller
10 IRQ Holder for PCI Steering
10 IRQ Holder for PCI Steering
11 Intel 82371AB/EB PCI to USB Universal Host Controller
11 Chips and Tech 69000 PCI
11 IRQ Holder for PCI Steering
12 PS/2 Communications Port (COM9)
13 Numeric data processor
14 Intel 82371AB/EB Pci Bus Master IDE Controller
14 Primary IDE controller (dual fifo)
15 Motherboard resources

Don't know if that helps, but if anyone can PLEASE help me out here
I'm stumped and really hoping to finish this project correctly.
