Sorry this is very late, I stopped reading these lists for a while.

I've been using a tool called commit-patch.  It's supposed to work
with just about any SCM, but I use it with Mercurial.  It comes with
an elisp file to make it work with vc-mode.  The only trouble I have
with it is if you try to edit the patch in a way that should still let
it apply cleanly, it often complains and does nothing (but I've never
had it corrupt a patch).  It always works for me to selectively remove
hunks from the patch.

Before I used commit-patch, I used the Mercurial extension crecord.
