There is a new SideKicks version that was released for TFS 2008 and TFS 2005.

Personally I don’t see any amazing new functionality that was released with the new version, a few bug fixes the best new functionality that I could find was the search for users in the server.

Any way if you are SideKicks fan (And I know of many that are) than this link is for you:
