ok, nevertheless i tried the script of Shawe Ewahs and the one of yleetiny on a VAIO FZ31M.
unfortunately i do not know exactly what both solutions where supposed to do, but apart from the weird effect i got now when changing brightness with the FN-keys, the gnome-osd will not go over the middel, instead stucks there shivering, nothing else did work:
no gnome-power-manager-support
no dim when switching to battery...

in that case i would recommend everyone who got the same result to follow this how-to here:
