I previously covered Macaroni / Leopard compatibility. Basically, get version 2.1, which is a free upgrade, and read my previous message for more detail.
If you're using MondoMouse or Chimey though, you might well be wondering what's up. In short: the current versions of MondoMouse and Chimey work on Leopard as-is, so no upgrading is needed. As long as your Leopard install is one of the "upgrade" options (as opposed to "erase and install") you shouldn't need to do anything at all to keep using MondoMouse and Chimey.
