Look: it took you a few good days to simply *report* that the hack I
gave you was helping. Surely you can similarly wait for a few days for
the interested parties to spin proper patches and *test* them?

And if you really cannot wait, feel free to backport this change to
whatever stable release you feel needs to be fixed and post the
result.  I promise that I will review it. After all, you are so far
the only person with both the HW and the problem.
