That's weird, and likely the cause of your problem.  The PCI interrupt
couldn't be routed for the first chip function, but could be for the
second.  As a work around, try adding:
	hw.pcic.intr_route=1
	hw.pcic.irq=0
in your /boot/loader.conf file.  This forces ISA routing for all.
Having one function of the bridge do ISA and the other do PCI is
likely one of those "can't do it in hardware" sorts of things, at
least for the card status change interrupts, which are weird..
