do you mean, you can not get original bayer patterns from camera, or you can not get video at all? If the first variant, then this is an unfeasible enhancement request, as many camera drivers just do not expose this functionality. If the second one, try the latest snapshot of https://code.opencv.org/svn/opencv/trunk/opencv or https://code.opencv.org/svn/opencv/branches/2.2/opencv.
