xM camera resolution higher than 5MP?

The xM SRM mentions using cameras up to 5MP on the camera header.
From what I gather OMAP36xx can do image capture up to 12MP.
The OmapZoom Blaze seems to have a 8MP Sony camera sensor.

Has anyone done it or aware of 8MP/12MP image capture on the beagle
using the camera header?

Any links/thoughts/suggestions would be appreciated.

I am not aware of anything other than what is listed in the System Reference Manual.
