Default hardware issues for battery stats and charging

Does anyone know what files android uses or where I'd have to look to tweak the system into thinking there's a 30-pin charging port on the device? Would it be possible if a driver were created?

I just flashed CM11 and the statusbar battery icon just shows a full circle with a "?" in the middle. When I go to about tablet > status... battery status is "unknown" and battery level is "0%".
