The slight chance of a lockup appears to be 100%. System boots fine either
with or without the card inserted until pccardd runs and detects the card
(Linksys Combo Ethernet E2CT). It gives me a messages saying that the card
was detected, and then locks hard until I remove the card, at which point it
gives me a fatal trap 12 while in kernel mode and reboots.

I got this far by turning off CardBus support in the BIOS and doing as you
said...it detects the control interrupt as 3 and claims that pcic0 is
operating in kludge mode. Before I turned off Cardbus, the PCI->Cardbus
bridge was detecting at IRQ9, now it's at IRQ 10, which appears to be the
IRQ the E2CT is trying to work at.

Oddly enough, this also caused the USB support to break, it seems. Before I
turned off the CardBus support, it was detecting fine. Now it detects ohci0
at irq 255 and tells me to switch on USB support and to turn off PNP-BIOS
support....which is not an option.

Just remove the irq xx from the pcic line.  Go to polling.  It
slightly increases the chance of a lockup, but only very slightly.
