Just wanted to say thanks for this guide, I used it for my Intel DZ77BH-55K Motherboard!
my specs:
Intel DZ77BH-55K
Intel Core i7 2600k
8GB Corsair 1600mhz Ram
Nvidia Geforce GTX 560ti
Crucial M4
since I have an Nvidia card I had to boot with "PCIRootUID=0" to get to the installer screen, after that I installed on my SSD without issue. When It reboot I selected the hard drive I installed on, then once again "PCIRootUID=0" to boot into OSX.
Once in OSX I ran MultiBeast for 10.8 and selected:
"User DSDT"
No-DSDT ALC898
Intel Ethernet
FakeSMC
Mac Pro 3,1
Core i7 2600 SSDT
after installing those I closed MultiBeast, then downloaded the .kext for AppleIntelCPUPowerManagement you posted:

I used KextBeast to install, then I ran disk utility and repaired permissions.
Restart
Once back in OSX I ran software update and got 10.2, everything is working great! However in system profiler my SATA showed up as unknown controller, so I followed this and made the change:

everything shows up perfect now!
my geekbench however is only 11,800. I dunno if that is normal or not for my Specs???
In the Bios I enabled Deep s4\s5 sleep, AHCI, UEFI Boot
One last thing, when I used multibeast to enable 3rd party USB 3.0 the system wouldn't boot! It would freeze right at the login screen where you enter your password to enter OSX. I had to delete everything, and re-install because of that!
