My experiences with PCI BIOS suggest that routing a pin that's already
routed will produce an error return from the call, but the pin will
still be routed and interrupts will still work.  Some systems
apparently report an error also when you reroute an interrupt after
suspend/resume in APM as well.  Unless it causes problems, chances are
excellent it can be ignored.
