I managed to install all of this including the kext in this guide. Everything works perfectly and i can even update to 10.8.2, my only issue now is that when the screen goes to sleep, i can't recover anymore.... i get a blackscreen if i move my mouse around i see the pointer but that's it... i have to hard reset the PC. Please help me.
Anyone? please i need help with this sleep issue. I understand it is probably due to the nullpowermanagement kext but if i remove i wont be able to boot into osx anymore... Can someone explain the steps for me?
