I eventually hired out for this and got it working very nicely:

https://github.com/fastr/linux-2.6 - kernel with fsr172x patches
https://github.com/fastr/media-ctl - omap-isp pipeline configurator (patched)
https://github.com/fastr/yavta - v4l2 test application (patched)

Most of the patches will make it upstream.
