Hi mnorthern!
I did everything as you said, but the brightness does not work. Scroll brightness and keyboard shortcut work, but the brightness does not change. Could you see my dsdt. Any  ideas?
Brightness wake after sleep also doesn't work.
Thank you for your help.
DSDT and ioreg http://cl.ly/2M451I3W0J3Q

@mnorthern, can you look at my dsdt. I get BAR1 value - F7000004. What should be the operation regions? I can get brightness scroll, but brightness not changed.
DSDT, DarwinDump, ioreg here - http://cl.ly/2q2G3i1y3R0t

UPD: After update to 10.8.3 on my laptop QE doesn't work. Maybe this is the reason.

@trik82, after update to 10.8.3 your video is works? Can you give your HDGraphics kexts?

@mnorthern, can I get BAR0/BAR1 using DarwinDump?

Ok. Thanks! I try it.
You update your system to 10.8.3?
After updated in my system QE doesn't work. I changed kexts to old, but nothing changed.
