Hm, it does look very odd.  It looks like it has something to
do with <choice> working differently for some reason.

In xconfig, I set all of the View Options and when I click on one
of the periph. controllers, it says

	depends on =y && PCI

but if I back up to -git7, it says

	depends on <choice> && PCI

I'll keep looking.
