I followed this tutorial and used slayer's dsdt file and proceeded to step 8 where I tried booting to the snow leopard hard drive. Unfortunately, it hangs on this error:
ACPI_SMC_PlatformPlugin::start – waitForService(resourceMatching(AppleIntelCPUPower Management) timed out

Here are my system specs:
Mobo: eVGA x58 Classified 141-BL-E760-A1
CPU: Intel i7 920 - 2.66GHz
RAM: Corsair 6GB DDR3 1600MHz
GPU: MSI GeForce GTX295 1792MB

I prepped this drive on my MacBook running 10.6.1 through a SATA to USB enclosure.

Any ideas?
