I had the same problem on an IBM A30p with 5.1. Do this
at the boot loader prompt:

set hw.pci.allow_unsupported_io_range=1

That should take care of it. You'll need to place the part after
'set' in your /boot/device.hints file after you complete the install,
otherwise your kernel will continue to fail at boot.

HTH.
