Ran into the same problem.
Upgraded from an up-to-date Gutsy to Hardy yesterday. No alpha, beta or RC versions of Hardy installed. Hardy distribution from the ubuntu.mirrors.skynet.be mirror. Numpad broken after the upgrade.
Same solution: switch "allow to control pointer using keyboard" to off. Found this article very helpful: http://nancib.wordpress.com/2008/03/17/fixing-the-borked-numeric-keypad-in-ubuntu-hardy
