Input: i8042 - add Sony Vaio VGN-FZ240E to the nomux list 

On this model, when KBD is in active multiplexing mode, acknowledgements
to reset and get ID commands issued on KBD port sometimes are delivered
to AUX3 port (touchpad) which messes up device detection. Legacy KBC
mode works fine and since there are no external PS/2 ports on this laptop
and no support for docking station we can safely disable active MUX mode.
