I have a few images you, or anyone with an affected system, can try
without needing me to be in front of the machine.  (If this doesn't work
then we can see if we can make arrangements.)  These are the usual
hybrid CD/USB images created by grub-mkrescue, despite the .iso
extension.  The patch files alongside them are each relative to
http://bzr.sv.gnu.org/r/grub/trunk/grub/ revision 3006, built with
'./autogen.sh && ./configure --with-platform=pc && make &&
./grub-mkrescue --grub-mkimage=./grub-mkimage
--override-directory=grub-core -o 1.iso' (etc.).

  http://people.debian.org/~cjwatson/tmp/grub-pci/

Boot each of the images, which should result in a GRUB prompt, and run:

  set debug=pci
  lspci

The first image should hang; I'm interested in the last bus number
printed.  The second may or may not hang, depending on the exact point
things go wrong; again, I'm interested in the last bus number printed.
If my theory is correct, then the third should complete successfully;
either way, I'd like the full output from the third image (sorry, it may
take a little while to transcribe).

Thanks,
