Since my key was getting old I have generated a new key that is stronger than the old one I was using, and has different cipher preferences. It’s also for use at the keysigning at LCA next month. There’s a transition notice signed by both the old and new keys here: http://mwh.geek.nz/files/key-transition-2009-12-22.txt
The key ID is FEC39745 and is on pgp.mit.edu and probably others.
