If this was the case for light how come that ISO 1600 on a GH2 in video mode will have exactly the same light gathering capability as a 5dmk2?

Because the 5dmk2 is line skipping (not using it's whole sensor) to get the video resolution down to HD spec.

This is also why the 5dmk2 (along with many other HD capable dslrs) have aliasing problems, because as the lines are skipped detail becomes jagged.
