Your BIOS is assigning a memory range to the card that we don't believe
the bridge passes through.  Our check is bogus because (as you see) the
range is actually legitimate (and we booger up some calculations).  Add
the PCI_ALLOW_UNSUPPORTED_IO_RANGE option and this should go away.

You should have bought a 3ware controller. 8)

or that we are to stand by the president, right or wrong, is not
only unpatriotic and servile, but is morally treasonable to 
the American public.  - Theodore Roosevelt
