Thanks for this amazing tutorial man_on_the_oak!

I follow all the steps letter by letter, but after I reboot with dsdt compiled I and NullCPUPowermanagent.kext deleted, I got a kernel panic like this:

"CPU 0 has no HPET assigned to it"@/SourceCache/AppleIntelCPUPowerManagement/AppleIntelCPUPowerManagement"

I'm googled but I didn't found any solutions so I ask you

I have the same PC subject for the CPU. It's an P4 T4300, the rest of the specs are the same

Thanks for everything!

ps; I'm sorry for my english; I'm spanish young men xD
