Unrelated comment: since tboot now has a PE build
(http://hg.code.sf.net/p/tboot/code/rev/5c68f0963a78) I think it would
be time for OpenXT to drop the weird efi->xen->tboot->xen flow and
just do efi->tboot->xen. Only reason we did efi->xen->tboot was
because tboot didn't have a PE build at the time. It's a very hackish
solution that's no longer needed.
