I don't know of one, but I'm pretty sure you could hack something with a small enough wacom tablet if you really wanted. I used a wacom tablet for some time when my mouse broke and the store didn't have the one I wanted. Anyways, trackpoints are readily available and can easily be added even to custom keyboards. They're even more handy than trackpads in my opinion, since with a trackpad you still have to leave the keys while you can install the trackpoint at the hjn-join or the fgv-join (or whatever the layout puts there, for me it'd be nrt and aeä).
