I could be insane, but I'm pretty sure it works at least in dom0 right
now.  So disabling it across the board means a loss of functionality for
anyone wanting to run dom0 on their laptop which isn't really needed.

Having it dependent on either XEN_PHYSDEV_ACCESS or
XEN_PRIVILEGED_GUEST, on the other hand, doesn't seem unreasonable
