Hi all,

I confirm that your module (first version posted) works fine with my setup:
Asus N61JV-JX011V
GeForce GT325M + Intel GMA HD
Archlinux kernel 2.6.34 with Openbox

It stopped the nvidia GF card successfully using the 
"\_SB.PCI0.PEGR.GFX0._OFF" method.
I made a picture 'battery capacity vs time' just to illustrate the effect.
During my tests, I had always the same applications working plus wifi.
The gain in time increased from 1h40 to 2h20 approximately, which is 
very cool!

Thx a lot Michal.
