IRQ conflicts on RELEASE 5.2.1: Thinkpad 600x and PCM100

Can someone give me a clue on how to identify IRQ conflicts on 5.2.1?

But, here's the bigger problem:

I've been crusing around the list archives and technical documentation 
for about a week now trying to get my ThinkPad 600x working with a 
Linksys PCM100 card.

I'm still getting device timeouts (which suggests to me an IRQ 
conflict).  Here is my system configuration:

in /boot/loader.conf:
	hw.pci.allow_unsupported_io_range="1"
	hw.cbb.start_memory="0x20000000"


in /boot/device/hints, all references to hint.ed.0 are commented out.  I 
have tried setting the following values (rebooting with each change) 
with no result:

hint.ed.0.at="isa" & hint.ed.0.at="pci"
hint.ed.0.port="0x280" & hint.ed.0.port="0x100"
hint.ed.0.irq="10" & hint.ed.0.irq="3"
hint.ed.0.maddr="0xd8000"

Any further help in getting this card working would be apprecitated.

Thanks.
