Yes, but how is this related?  The patch only solves a mismatch between
data formats, which would have to be fixed anyway.  The surface would
still be experimental, but at least it would more or less work.

Are you going to commit all of them or only the ones that are mature?
I'm afraid that my branches will have some conflicts if you apply on top
of them the ones that I thought were not yet ready.

Great, feel free to cherry-pick them into your tree too.  It would be
great if you took one of my branches*, diff the tip of my master branch
against yours, and separate the remaining diff into logical pieces that
can be applied independently; Emacs diff mode is easy to learn even if
you're a vi user and will be your friend.  This will also remove things
such as the MMX/SSE patch that you reverted due to licensing problems
but is actually still in the repository (just not in the HEAD).

  *You will have the same conflicts independent of whether you use
   branch master (which includes changes of yours that I reviewed) or
   branch paolo.  The changes in master..paolo only touch stuff that
   you had not modified.
