Cool, now we're talking. I'm away from my machine for today (Happy Thanksgiving everybody), and then I have piles of homework, but when I get time, I'm going to be going over this guide a few times. It has something in it about the legacy kext not working right if you put tabs in it instead of spaces when you indent, so that might be a place for me to start. We need to get CStateInfo and CPUPLimit showing up in IOReg under CPU0, Apple_SMC_Platform or whatever. I suspect that somehow, maybe because of something I'm doing wrong, or maybe because of the bios, that C2RC5 isn't loading the C-States even though it says it is.
