One would be to keep an "enabler" count.
If the device is enabled at boot then set it to one (video, legacy IDE etc) and it never gets back to zero. Otherwise set it to zero and it goes up and down with the last [ab]user clearing it to zero and turning it off. That also deals with the "who disables" question for power mismanagement where the same problem occurs
