Sometimes, it's possible to make FreeBSD output the same IRQs in dmesg,
but the device still won't work (often because the BIOS has locked the
IRQ to, say, IRQ 10).

Depends. Some devices work with IRQ 9, and others don't. I think
people have reported that the Wavelan card can use IRQ 9 (on older
versions of FreeBSD, though).

At this point, I think you need to make sure that the pcic device
is working; you don't need any more free IRQs at the moment. You've
already got a free IRQ (5 or 9) to use for the Wavelan card, and you can
always free up more, later, if you need more (but you don't, if all you
want to use is the Wavelan card).
