The only sparse checkout support I'm aware of is a project that appears to
have been abandoned in mid-2008. No code relating to sparse checkouts or
subtree checkout support has ever made it into the git development repo,
as far as I can tell. (I just now looked at the lastest version of the master
branch from git://git.kernel.org/pub/scm/git/git.git).

I would not count on ever getting subtree checkout support in git. It
just doesn't work with git's model.

That said, there are methods that allow you to git a similar
effect with a little bit of extra work. One example is git-subtree
(http://github.com/bronson/git-subtree).
