Thats correct. The patches have not been merged. I no longer have the
hardware available and have moved away from the project that needed it,
therefore I was unable to carry with the patches (they were still under
review). It'd be great if you can resubmit those. Make sure they apply
cleanly to the latest staging branch (?). I think Greg had asked some
question regarding during the review, it would be good if you can pick it
up from there. GKH (who's on this list too) can weigh in more on this.

Good luck.
