Personally what I would do is use git rebase instead:

# WARNING: untested.  back up your repo first!
cd my-repo
git fetch ../linux-2.6.32.y v2.6.32.14
git branch b FETCH_HEAD
git fetch ../linux-2.6.32.y v2.6.32.12
git branch a FETCH_HEAD
git checkout b
git rebase --onto master a
# now your branch b should be master + the patches from a..b

Looks like Shawn answered this question.  In any case, the answer is git-reset.

Have fun,
