To follow up, Jakub's approach works great without
requiring any changes to Git.

For example, the following test script always
produces the same commit ID:

----
export GIT_AUTHOR_DATE=2005-04-07T22:13:13
export GIT_COMMITTER_DATE=2005-04-07T22:13:13
mkdir -p /tmp/test
cd /tmp/test
rm -rf .git
git init
echo "Test" > README
git add README
git commit -m "test"
git log
----

As expected, commenting out the 2 export lines results in
different commit IDs each time.

Case closed.

Thanks, Jakub!
