This sounds like what I want to do but from the other way around - use the Freerunner to connect to a remote Fedora machine with a Virgin (Australia) mobile broadband that is connected when I leave it but eventually disconnects some hours or days later.

Without CSD the most reasonable option imho would be to keep a persistent connection over GPRS to some internet host you control and use it as a proxy. An alternative would be to establish GPRS connection upon an incoming (voice) call or message but that'd be more complex and fragile to set up.
