While reading Kevin Rose's page I noticed a few more blog/CMS type systems mentioned, both written in PHP.

Don't know if they'll fit your needs, but...

WordPress
&
pMachine

Edit: Oh, and if you read the comments, there are links to others as well.
Edit (again): Wow. Mambo is a nice one (check out the demo site).
