Solve the backlight problem with TinyCoreLinux #18
Description
The display overlay works great, but since TinyCoreLinux needs the respective drivers pre-loaded (and by default there's none), we need to figure out what drivers are needed to handle the backlight GPIO pin.
Workaround:
Just unplug the backlight pin, so the LCD backlight stays on max brightness.
