Sansa AMS: Time has shown that switching between 16 and 32bit mode costs much time (due to the micro delay needed), so do 32bit transfers unconditionally for lcd updates at the cost of updating slightly larger rectangles (gives upto 15% speed up, nearly at maximum now).
Unify this optimized dbop transfer function and re-use it more often (it still handles 16bit transfers).
