I've not investigated more thoroughly yes, just posting in case something obvious leaps out at someone. The automated test is currently bisecting the issue, once it is done I'll let you know the result.
If I'd read a bit further through my Monday morning INBOX I'd have found: http://lists.xen.org/archives/html/xen-devel/2014-11/msg00001.html
which indicates that the bisector has fingered:

Sorry about that - I missed one of the stack offset conversions in the PNP part of that change. The fix is below and I just pushed it to the main repo.
Thanks for catching it.
Thanks for the quick fix!
FYI the next Xen osstest run didn't suffer from this issue, thanks.
(in case you go looking at the results, it did fail for other Xen related reasons, nothing to do with seabios, but this issue is definitely gone.)
