I do have an updated patch that I've been carrying in my tree, but it
still is too
large, with too  many touches to be ready. Finishing it was in my 1.8 tasks, and
I've been working with it as part of my kernel developer changes. I can probably
fire something out by end of week (I haven't tested it in over a week, so it is
likely broken again).

Let me check, and get back to you on that.
