The fix I proposed (also attached to this email) fixes a bug introduced
in the pci domain patches in greg's tree, specifically this patch:

	gregkh-pci-x86-pci-domain-support-struct-pci_sysdata.patch

I believe that my fix is complete in the context of those changes, in
that it returns the original semantics.  As greg points out this exposes
a couple of places where we do have proper domain and node information
where it is not supplied.  I have a patch or two waiting to be tested
which tries to fill in some of the gaps exposed, but the boxes I was
testing on have dropped off the network and am waiting for that to be
fixed before sending them in.  That said I think that if the pci domain
patches are accepted then this minimal fix should be applied with them.
