Perhaps you can read about "git replace" in my article:

http://www.kernel.org/pub/software/scm/git/docs/git-bisect-lk2009.html

and/or my related presentation:

http://www.linux-kongress.org/2009/slides/fighting_regressions_with_git_bisect_christian_couder.pdf

I think in the long run it's much better to use git replace rather than 
notes, especially as replace refs for bisecting could be in their own 
refs/replace/bisect namespace. I may take the time to implement that soon 
if you or other people are interested.
