Omnivision camera drivers for BeagleBoard XM with Angstrom

Are there any Omnivision camera drivers for the BeagleBoard XM? I
intend to use the camera interface port to connect a camera module to
the BeagleBoard XM.

Alternatively does any reference driver exist for this platform I
wouldn't mind porting it to suit the Ominivision image sensor?

I've found that Leopard Imaging develops camera modules for the
BeagleBoard XM, are the drivers freely available for download??
