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. Thanks, M. -- Without deviation from the norm, progress is not possible.
