Yes it does. I assume on the new models with both, an Intel and a Nvidia 
graphics adapater, backlight is always controlled by the Intel 
mechanism: "only" the graphics adapter itself is switched.

So, what do you mean by that? :-)  But to check on it anyway: it is 
truly your mbp_nvidia_bl module responsible for the working backlight 
control. First, I tried to control backlight with the Nvidia mechanism - 
it does not work (no reaction).
By the way: how did you find out about the i/o ports -  did you extract 
this information from the OSX driver? 0xb2 / 0xb3 seems to be an 
interface for SMI calls... but I couldn't find anything about 0x52e or 
0x52f.
I mean are they at all Intel/Nvidia specific? or did Apple just use one 
method for all their Intel only models and the other for all their 
Nvidia/Intel models?

It works on MacBookPro6,2 out of the box (ata_piix):
