TKLOCK_ENABLE was used for the tklock in earlier versions of Maemo
(where you'd press the power button followed by center button to unlock).

The flicker key is the lock key available on the N810 and N900; the
770 and N800 doesn't have one.
Called flicker because it's not a slider key -- it "flickers" back.

And indeed these parameters are ignored.
