Actually, if you want something that does not change all the timestamps, 
and that does only trivial merges (i.e. no conflicts), you may have luck 
with something like this:

	test $# = 2 || {
		echo "Usage: $0 <commit> <branch>" >&2
		exit 1
	}
	GIT_INDEX_FILE=.git/tmp.index &&
	export GIT_INDEX_FILE &&
	git read-tree "$2" &&
	git diff "$1"^! | git apply --index &&
	tree=$(git write-tree) &&
	msg="$(git cat-file commit "$1" | sed '1,/^$/d')" &&
	commit=$(echo "$msg" | git commit-tree $tree -p "$2") &&
	git update-ref -m cherry-pick-2.0 "$2" $commit

Totally Untested(tm),
