consider:

: pccard0: <16-bit PCCard bus> on cbb0

: pccard1: <16-bit PCCard bus> on cbb1
: $PIR: ROUTE_INTERRUPT failed.
: cbb: Unable to map IRQ...
: Entry 1: Device 0:2:0 Slot 0 (on-board)
:         INTA: 60h routable irqs: 3 4 5 6 7 9 10 11 12 14 15
:         INTB: 61h routable irqs: 3 4 5 6 7 9 10 11 12 14 15

I think we're trying to rotue wire 0x60 twice.  The second try seems
to be failing.
