  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.
