Please note, I have not tried this myself!

Foundation Forum member ‘RpiName’ has just posted an announcement of a Video4Linux2 driver  for the camera board. This should open up a whole raft of possibilities. The V4L driver SHOULD expose the camera on /dev/video0, so take a look and have a go at installing it. Visit the code repository to find out how to install.

Please note, again, that this is an unofficial driver generated by the community rather than the Foundation.
