The et8ek8 sensor driver datasheet is available at http://www.retiisi.org.uk/~sakke/foo/SMIA95_AF_camera%20module_APL_090511.doc.

The camera-firmware branch contains the camera-firmware source that is needed to generate register list binaries for et8ek8 and smia sensors used on N900.

Current status: the adp1653 patches and the flash interface patches are no longer in this tree since they have been applied to media-tree: http://git.linuxtv.org/media_tree.git staging/for_v3.1 branch, where they should find their way to upstream Linux 3.1 kernel.
