Well ... still doesn't work properly but getting closer.

The Option does active dual head. Just the timings are (still)
incorrect. I got a picture, but with a lot of artifacts with a new
modeline calculated for 2560x1600 at exactly 60Hz. So this is odd.

It means "out of scan range" afaik now ...

Documentation on my progress can be found here:

Anyone got a clue where Apple documented correct timing for the cinema?
Or does anyone know how to extract this information, maybe from running
macosx?

Thanks and good night!
