Well, I guess it's doable, since do_suspend_lowlevel also needs
to restore processor context upon S3 failure (function return from
acpi_enter_sleep_state instead of from wakeup stub).
From a quick look, it seems that all the instructions in the restore
code are ones that Xen will trap and emulate; but with this kind of
thing, its all in the testing...
