What do you mean "not related"? Then you have a partial workaround. This whole thing is trying to fix a hw bug so of course it is related.
Once you do the "full" workaround, along with the part which reintegrates the counts and thus completely fixes the issue (I believe), then you don't need to disable it at all because disabling it doesn't make any sense then. See what I'm saying?
This is the whole point Matt and I are trying to make: if the *full* workaround doesn't have any noticeable disadvantages, then you don't need to add a disable-mechanism due to the can of worms opening if you do.
How you get this upstream to ease the review is a whole another story and I applaud your desire to keep things clean.
