I just found one of my favourite games, Warzone 2100, on the net, Pumpkin released the source and a team ported it to openGL and SDL for Linux, if the second cpu could be coaxed to pretend to be a 3D Ogl style GPU (RTS doesn`t need anything like 60fps so this should be possible) then it would be possible to port Warzone to the GP2X and you have a single/multiplayer commercial standard rts available for the GP2X and the possibility that someone could even add other games to the basic engine, for example it wouldn`t be too hard to make a CannoFodder-alike game using the Warzone engine (imo), any takers?
