S/L/E = Systems/Library/Extra
7a ...select GraphicsEnabler...NO! I wrote in my guide that you have to disable GraphicsEnabler ("GraphicsEnabler=No" in org.chamelon.boot.plist) because the outdated version that comes with iAtkos can't handle the HD3000 correctly in the Lenovo. When you have your lion up and running then you update Chameleon to 1650 or newer and then you can (and should) enable GraphicsEnabler in org.chameleon.boot.plist.
10. Install ALL the kexts in my first attachment (all BUT SleepEnabler!) to S/L/E with the help of KextWizard. Update to 10.7.2. Install AppleHDA and IO80211 kexts again. Then remove NullCPUPowerManagement.kext from S/L/E and install modified power management kexts from my second attachment (again with Kext Wizard). You must repair permissions of the whole S/L/E folder then and rebuild the kextcache (can do that with KextWizard too). –– Finish (hopefully ) –– And in the future if you update to 10.7.3 you must install NullCPU -before- you update. After update (and reboot) reinstall Audio, Wifi, PowerManagement and remove NullCPU.
