would cool to get an Ack from ChromeOS-people concerning the
license change to GPL2/X11 - as with the dts before

Also if someone else should be designated as author I would be happy
got get a shout about that :-) . I did take Chris as he was the one
submitting the initial mickey dts to the chromeos tree.

And of course it would be cool if anyone could test that on an actual
mickey device.
