Check jaunty-backports first, if not there's probably a PPA. Of course wtih a PPA it's essentially unverified and not security patch supported. I really wish there was more of a "auto-backports" service for the most popular distros - basically like doing a nightly build of upstream except it's a package. And of course untested and unsupported in every way.
