Even if the processor is the same, the screen certainly isn't, and it's going to have another controller. Only that little change is a lot of work of hacking the source code.
the screen is exactly the same from a port view (same number of pixels) however the controller is different resulting in a different driver and 8 gray scale levels. Partial screen updates in defined regions is now supported but could possibly be ignored for now. The processor is the same only faster. They keys are mostly the same but the right size has a scroll-wheel. Depending on the API availabilty and documentation from Jinke this could be easy or hard.
