First thing I've noticed: You need to define a numa node so you can
pass a valid numa node to the pxb-device. Guess that is ok as the whole
point of this is to assign pci devices to numa nodes. More complete
test instructions would be nice though.
Second thing: Booting with an unpatched seabios has bad effects:

"PCI Bus 0000:10" is bogus and "PCI Bus 0000:00" isn't there at all.
