Excellent.  I've committed the 2 bugs needed to fix your box.  However,
there is another bug that this exposed that I'd like you to test.  Can you
update to the latest HEAD, apply the updated pcib_debug.patch, and boot
with 'hw.pci.pcib_clear=1' set from the loader?  That should exercise the
bug I'm worried about and see if my fixes for that (recursively growing
windows) works correctly.
