@osxf33k,
Thanks for the kind words. Yes, last I checked Andrew was adding the mm6,2 StepContextDict to his fake smc kext which achieve the same result as using the kext provided here (just a dummy kext that overrides the oem StepContextDict from whatever platform you're using). I prefer a modular approach.
You shouldn't need to patch the AICPUPM kext because your CPU is IvyB-EP not SandyB-E. However, if you actually get better results from doing, then go for it. I don't logically see how it could help w your CPU though.
You could use the config.plist I provided in my golden build for Eric and also use the Dsdt guide I linked to in that build to patch your dsdt as opposed to using Andrews ssdt but that just comes down to your preference. With a patched dsdt you need to re-extract and patch a new dsdt every time you want to update the bios.
Wake from sleep works fine for me. I did however brake it and have the same symptom as you (unstable sleep) when I updated my bios to the newest one for the r4e. I think the bios chip actually went bad becaus when I switched to my 2nd bios chip (r4e has 2 chips) and updated it, wake worked fine. I haven't gotten around to replacing the 1st bios chip to see if that fixes it for bios1
