How to stop vibration while phone (Gingerbread) turns off?

[AC Question]

While my LG-P500 (Gingerbread 2.3.3) turns off, it sets off an earthquake! -- Really, I can even feel my mattress vibrate from 6 feet away, apart from hearing it across the room!

I don't know what genius mind had invented this "feature" (this problem was not there with 2.2.2) ! But how do I turn it off? Thanks.
