>Description:
	On my laptop it appears impossible to make use of irq 5
	with the PC card stuff, both for the controller and for the
	cards themselves.  I have a vague suspicion that some other
	device is lurking at that IRQ, such as the audio hardware, but
	I don't have my reference material handy to check.  And, no,
	we don't have a driver for the audio hardware, it's an ESS16888
	or something like that.

>How-To-Repeat:
	Try to use the PC Card hardware on a Dell Latitude XPi/CD,
	observe that any PC Card hardware which gets irq 5 assigned
	appears to be dead.

>Fix:
	This fix permits the user to manually tweak the irq-valid
	masks both for the PC cards and for the PC card controller.
	It's entirely conceivable that a more user-friendly manner
	to configure this should exist.
