I have a MacBook2,1 (Early 2006) with a C2D 1,83Ghz. but I recognized one disadvanced:\nBy default, the AppleIntelCpuPowermanagment.kext lowers the voltage of the cpu down to 0.775V on idle at 996Mhz. Coolbook doesn't do this anymore. My cpu is stock at the voltage I set.\nIt used to work with SL.\n\nBut anyway, thanks a lot!"
