I don't have any intel boxes that I could readily try it on.

I just noticed that my pv domain suffers the same problem (won't shut
down etc) and actually leaves 2 pages instead of one:

(XEN) Memory pages belonging to domain 1:
(XEN)     DomPage 0000000000213789: caf=00000001, taf=00000000e8000001
(XEN)     DomPage 0000000000213788: caf=00000001, taf=00000000e8000001

I wonder if it's possible that some Debian code is left around somewhere
on my machine... any suggestions for where that could be that would
cause a problem with Xen? It just seems to me that this problem is
severe enough that if it really was a problem with Xen and not my setup
that others would have noticed it too...
