I have the same issue, here is the detailed description of the problem: http://answers.ros.org/question/105296/primesense-carmine-not-working-under-groovy-but-works-in-fuerte/

I also encountered this problem today, after updating to the latest libopenni-dev (replaced openni-dev) and all the depth_registered/points are filled with NaN. I am running openni_launch/openni.launch from ubuntu 12.04 32bit....

Yes, this problem was reported only to appear on 32-bit systems. Still don't know why.
