I've got a stable OS X 10.8.2 Install on my Samsung RF411, which runs an Intel Core i7-2630QM. However, there's one really pressing issue bothering me-the battery life on my notebook when running OS X. I get about 3.5 to 4 hours in Windows when my notebook is idling. However, I get barely 2 hours when in OS X. Also, when under load in Windows, the CPU uses Turbo Boost to increase its frequency from 2.0 GHz to 2.9 GHz, but nothing of the sort in OS X. Furthermore, to add on, I only have 2 P-states reached as shown in MSRDumper.kext: 8 and 20. I have a feeling all this is due to badly configured CPU power options by the OS.
I have seen and heard of many things, like NullCPUPowerManagement.kext (which I have currently installed), a patched version of AppleIntelCPUPowerManagement.kext, SSDTs, and SpeedStepper.kext.
I have set up my notebook with a patched DSDT and SSDT, and patched AppleIntelCPUPowerManagement. However, my notebook kernel panics at the end of verbose boot, where everything else, right down to my trackpad and LAN kexts are loaded, and just before the desktop GUI screen appears, I get a kernel panic that backtraces to AppleIntelCPUPowerManagement. How is this possible? Please help me!!!

Where are your DSDT and SSDT from?

If somebody tries to support you with your issues, you don´t read the posts. Look at post 4 in your thread. A Smbios of an MBP with only i7 2...m cpu does normally not support i7 2...qm cpu´s. You should at first change to a correct personality for your laptop.

Anyway, I've partially solved my problem... I moved IOPlatformPluginFamily.kext to another folder, and it booted successfully. However, I get NO Turbo Boost and only 2 P-states, 8 and 20, most of the time. It very rarely shows P-states 16, 17, 18 and 19.

Besides, linking to off-site images is generally a bad idea, because you never know if said image will still be at the same URL tomorrow.
If you want to show someone a screenshot, best practice is to click "use full editor" and attach it to your post.
