  SVN rev 196520 on 2009-08-24 21:51:46Z by jhb
  
  Tweak the way that the ACPI and ISA bus drivers match hint devices to
  BIOS-enumerated devices:
  - Assume a device is a match if the memory and I/O ports match even if the
    IRQ or DRQ is wrong or missing.  Some BIOSes don't include an IRQ for
    the atrtc device for example.
  - Add a hack to better match floppy controller devices.  Many BIOSes do not
    include the starting port of the floppy controller listed in the hints
    (0x3f0) in the resources for the device.  So far, however, all the BIOS
    variations encountered do include the 'port + 2' resource (0x3f2), so
    adjust the matching for "fdc" devices to look for 'port + 2'.
