Ah, I was looking at this just today, as it had been annoying me
greatly. This works for me, so:

However, I was wondering if it might be better to handle this by failing
the operation in xen and passing it back to dom0 to do. On the Pi you
send a firmware message to reboot, and that seems like too much to do in
Xen, but it would seem possible to send this back to dom0.
I don't think this is possible in the current setup. Xen will usually
restart the platform if Dom0 requested a clean reboot or crashed. So the
domain wouldn't be in state to service such call.
Just a
thought, as it might be a more general fix for other devices in the same
situation.
What are the devices you have in mind?
