I know in the canon system, the autofocus sensors and software are in the camera body. Different lenses focus better or worse depending on which body they're attached to. It seems however, that all you have to do is trick the body into thinking a lens has the appropriate electronics and the auto-focus confirm will work for manual lenses. I have an M42 lens with no onboard electronics, and the adapter that I use to attach it to my Canon has a little circuit that simply tells the body that a lens is attached, it doesn't actually communicate with the lens, but that enables af confirm.
