SVN rev 189404 on 2009-03-05 16:03:44Z by jhb
At least one BIOS bogusly includes duplicate entries for I/O APICs. The
bogus entries have a starting IRQ that is invalid (> 255, so won't fit
into a PCI intline config register). It had the side effect of breaking
MSI by "claiming" several IRQs in the MSI range. Fix this by ignoring such
I/O APICs.
