The old PCMCIA stuff is up and running, at least after I set
PCIC_ISA_INTR_ALLOC_MASK. With NpN OS on or off.,
But that's using legacy ISA PCIC-emulation addresses.
What I want is to get the cardbus code going. For that, both PnPoS=no
and the PCIBIOS patch set all the previousuly- unconfigured-IRQ PCI
devices to IRQ 9. Which may be correct for the Ricoh PCi-Cardbus
bridge on this Vaio; I can' tell, yet.

If the BIOS doesn't, then NetBSD has to. And since wired-IRQ devices
are fairly common, that means a Linux-style check to see at which IRQs
a devic can acutally generate interrupts, right?
