DT Swiss XM 1550 29 in lefty configuration after less than 100km in a brand new Cannondale Scalpel Carbon 1 29er 2012. These are standard equipment wheels of this bike.

I located the slackness in the front wheel hub. These are made of two parts, as you can see in the YouTube-Video
or this one

The slackness is between the inner and the outer part of the hub. Im pretty sure that i can feel a torsion between the inner and the outer part of the tricon hub.
The brake disc is not fixed to show, that the problem is not any possible torsion between a fixed brake disc, the hub and tightened screws.

Update 2012/06/01: My front wheel is completely replaced now. My dealer also located the problem between the 2 parts of the Tricon-hub. I denied hes offer to thighten the 5 locking screws between the inner and the outer hub-parts. I was the first person with this problem he said. I hope hes right and ill never hear this sound again!
