Seems to be working with a small hack to AppleIntelIntegratedFramebuffer.kext.
See Hotkeys page.

where is the "hot keys" section located that you say has the fix?
thanks

Is it possible for you to post the kext? I tried opening the binary inside the kext and can't find that value at that address. Thanks!
Nevermind, I'm just stupid and can't read HEX values, I figured it out. Thanks so much!
With the brightness controls working my estimated battery life goes from 4:00 with wifi to 7:00 and without wifi it goes from 5 hours to over 9! I don't know how accurate those values are but I'm hoping the increase is significant. Now I'm going to try to undervolt with coolbook and see how much battery life I can get. I'm using one of the 8800 batteries.
I just tried this. Edited a backup of the file. installed it with kexthelper rebooted. now it seems to belocking on bootup. Lights are still flashing occasionally, but the spinning thing for boot stopped.
No good on my 901.
Which did you do this on? When mods like this are posted perhaps we should list install and model as a heads up.

ok, I was able to boot into safe mode (-x) and it booted fine, I restored from a backup of that kext.
All is fixed and is happy … no backlight control. :(

Ok, looks like this was my bad. I added that byte, I did not edit it. it boots now.
its GREAT that this page has the solution for this. big up! keep the work goin … ill spread this …
thank you! for all those having problems with awakening the maschine from sleep, press one of the brightness-keys after waking it up. and voila you get the screen back on :) thanx codeeye for this one! great
With the file codeye posted, do we still need to make edits? How do you run the file? Thanks
I believe the file posted was a zip right? Just unzip the file, then use the kext helper to install it. I highly recommend using OSX86 Tools to backup your Extensions folder. You could also use OSX86 Tools to install the kext.
Anyone got this working along with speed-step? My brightness controls work now, but it will not turn the display back on after coming out of Sleep. It seems the system boots back up but no display.
did you press brightness up or down after coming out of sleep?
The screen is set to off when going into sleep, so you need to turn it back on…
Well I tried re-installing without speed-step, and now it doesn't even sleep properly, screen goes off, but the fan keeps going and the status indicator never even blinks as if it's sleeping like before..
This is another brightness alternative, especially since if your not comfortable with editing the hex keys

No, the software-based solutions like Brightness Control and Shades only make the screen darker by progressively darkening the colors that the pixels put out, rather than by actually dimming the backlight. You'll see what I mean if you use one off these software solutions and put it to the darkest setting. At that point, your screen is black, but it's still glowing, meaning that the backlight is still on. This may work for people who just think the screen feels too bright, but the key is that it doesn't save any power like hardware dimming does.
