MBP Trackpad, right click (two-finger tap) not working on Mac OS X Lion

Don’t know why but my MacBook Pro (early 2008 ~ MBP 4,1) won’t enable the two-finger tap through the trackpad preferences panel o_O?

Solution, from your console:

defaults -currentHost write -g com.apple.trackpad.enableSecondaryClick -bool YES

Then log out and log in again.
