The last set of changes in Jeremy's kernel are a set of patches I sent,
so the problem is most likely caused by my work.

A dmesg from both Xen and Linux kernel would be most helpfull. Also
a lspci -vvv would be nice.

And as Pasi suggested, booting the same kernel without Xen would
be most helpful.
