OK, I grabbed this.

I made a number of changelog changes:

- Rewrote it as From: Andrea (correct?)

- Replaced your acked-by with signed-off-by, as you were on the
  delivery path

- Hunted down Arthur's email address and added his reported-by and
  tested-by.

- Added cc:stable, as it's a bit late for 2.6.38.  The intention
  being that we put this into 2.6.38.1 after it has cooked in 2.6.39-rcX
  for a while.  OK?
