Now, Apple revealed quietly on its website a combo update for both Time Machine and AirPort, available only for Mac OS X 10.5.2. Unfortunately, there's no much information about it on the official page - all you can read is "This update is recommended for all users and includes compatibility improvements for using Time Machine with Time Capsule, as well as AirPort driver fixes," as well as a short description of Time Machine and AirPort.
Well, I guess if you need it, you have to grab it, and the official page I mentioned above is located here, but if you don't want to waste any second, you can simply grab the update file, weighing 10.4MB, by clicking on this link.
