I recompiled xen with make xen verbose=y debug=y debugger=y trace=y

And it still doesn't work, but the xm dmesg does give a little more info
then before:
(XEN) (file=extable.c, line=71) Pre-exception: fc53247e -> fc532534
(XEN) (file=traps.c, line=463) Page fault: fc532549 -> fc506fc0

Not too useful, but might give a clue.
