Something like this (replace MY_START_BRANCH with your starting
branch, and do this in a clone of your repository so you don't destroy
anything by accident):

        parent=""
        git rev-list --first-parent --reverse  | while read commit; do
                if [ -z "$parent" ]; then
                        git checkout -f $commit
                        git clean -fdx
                else
                        git diff $parent $commit | git apply --index
                        git commit -C $commit
                fi
                parent=$commit
        done

Have fun,
