HEADSUP: new pci irq routing committed

Thanks to all the testers.  The new pci irq routing code fixes devices 
for several users.  If anyone has PCI device problems (timeouts, etc.), 
let me know.  Send me the output of dmesg from boot -v and your ASL 
(acpidump -t -d > machine.asl)

Thanks,
-Nate
