Why not a custom ARM design, start with a beaglebone or rPi to breadboard your design and then send out to China for the board, then hot air down whatever you didn't have them do in Senjen. Otherwish you are forever stuck in driver hell with the nasty production android component environment. Cherry Trail is AMD64 so you can even do some wine compatibility of desktop windows programs for those situations where you need a specific closed app for whatever.
