Hmm, the patch should apply directly to the tree as of when I posted
this original mail, or any later one. I just tried a rebase, and it
rebased fine on top of the current -git as well. So I think the issue is
with your tree, sorry!

It would be great if you could retest! There are some minor changes in
there, and some extra testing definitely will not hurt.
