Fn+F4 still double taps the touchpad toggle.  Both input3 and input9 are still
sending signals when it is pressed.

Fn+F6 does register as KET_F16 now, but the LED on the keyboard does not
change.
I don't know if the keyboard LED driver even works on Linux.  I've never been
able to modify the brightness with any of these commands either.

Fn+esc registers as KEY_FN_ESC but it does not trigger the lock.

evtests are below for event3 and event9.
