I had issues with VoodooBattery cause the one that i had was only for 32 bit and seemed to give some weird sleep issues...
So started using AppleACPIBattery from leo.. Just took the Source from our long friend Chun Nun and changed it for 32/64 bit arch..
It works perfectly in 32 bit.. someone try it in 64 bit mode as well.. All Credits go to Chun Nun for making such a beautiful kext.. and mainly for providing the sources... Download the kext below.....
After the kext was installed and the OS was rebooted, KP happened. Can you send me your source? I want to study it and resolve this KP. Thank you.
