I just wanted to say thank you to everybody that contributed to this guide. I was able to load 10.8.3 on a Dell E6500 and everything has been working great for the 3 weeks that I have been using it. I did some minor adjustments from the original guide:
Moved AppleACPIPlatform kext from S/L/E into the RemovedExtensions folder. Kextcache would unsuccessfully try to build kernelcache for about 25 times everytime after initial boot (error not having _acpihwread and _acpihwwrite). The version being used was the one from E/E (copied to myhack.kext) anyway.
Changed UseKernelCache to "No" to avoid random KPs. I am ok with the slower boot time (~45sec on a 5400 rpm drive).
I had to use voodoopstate.kext to enable speedstep. Unfortunately, GeneratePstates=Yes wasn't enough on my machine and clock speed was at max even when not doing much. I don't think I get Cstates enabled even after being able to load AppleLPC kext. But, this was better than nothing. This also helped with operating temps (idle cpu around 45-50c and the heatsink is the older one).
Wish list (very minor):
Hibernation - Sleep has been working, but I am so used to hibernation on windows 7.
MIDI setup preferences to save - I get crackling sound on higher volume levels unless I switch speaker output to 16-bit, but unfortunately it doesn't save and I have to adjust as needed.
Again, thank you to everyone for sharing your knowledge!
