I'll finalise my KiCad layout (need to add the expansion ports in) and post it up on github at some point in the near future - I don't know gEda, but do know KiCad - I think KiCad is a little easier to work with for final manipulation, but you have to jump through a few hoops for the module definition and tying up the circuit diagram to real devices (once you get the workflow, it's a bit easier)
