Yeah don't use that other brightness guide as it uses ACPIBacklight.kext which is obsolete. You can also remove the GFX0 to IGPU rename from ACPI in config.plist too.
Displays looks right to me. From what I see in your IOReg you appear to be using both AppleBacklightFixup.kext and WhateverGreen.kext as I see both loaded. If so remove AppleBacklightFixup (and rebuild your kext cache) its code was incorporated into WhateverGreen some time ago and is deprecated. If fact the two might be conflicting and causing brightness control issues. After doing that and restarting check in System Preferences - Displays and see if you have a working brightness slider. Click on and drag it to see if it changes the screen brightness properly.
Alright I have removed the AppleBacklightFixup.kext and still have no brightness.
Guess these Arrandale CPU laptops are a pain in the buttox lol
