It's up to the DDX to decide when to call DEVICE_ON.  It's entirely
valid behaviour for a DDX to call DEVICE_INIT at startup (as from
InitDevices), but not to call DEVICE_ON until a device has been
explicitly opened by XOpenDevice.

I assume this is what Xorg does, but I haven't had a chance to look yet,
mainly because its input handling is a total nightmare.

Cheers,
