At the moment, is it still the case that X will be unhappy if there are
any DRI clients running when going through a suspend/resume cycle? If
so, it sounds like the server ought to reject a suspend (or,
alternatively, use the notification to kill clients).

In the future, I'd expect that some dbus-related system would be
preferable - that way X doesn't get special cased, and any application
with good cause could reject a suspend.
