>Description:
	If you boot with an unrecognized CardBus card, and then noting that
	it was not recognized, remove it the kernel will panic.

	It turns out in this case, sc->memt == 0x10000000, sc->memh = 0x200
	which seems rather fishy (memh of 0x10000000 is not valid on x86, at
	the least).

	I'm not sure how the handle/tag gets trashed.
>How-To-Repeat:
	Boot with unrecognized CardBus card in slot. (eg, the Intel Pro/100
	  Mobile adapter that's really a rebadged Xircom)
	Realize that the Intel-badged CardBus card is actually a Xircom
	Remove card
	Kernel panics.

>Fix:
	Unknown.
