Userspace initiates the suspend, so GNOME or whatever is supposed to
lock things at that point. I've heard talk of a uevent or dbus thing
to broadcast it as well, but I'm not sure of the status of that.
IIRC Android already has a hack like this; they don't want the fbcon to
ever be visible during usage...
