To remove IntelCPUMonitor, find FakeSMC.kext and ctrl+click to show package contents. Inside, you'll find Plugins. Delete them from there. You'll probably have to repair permissions afterward. I'd also boot with -F to reload the kext cache.

Go to /System/Library/Extensions

Delete kexts beginning with AppleHDA in their name. Empty the Trash.

Install VoodooHDA.kext and AppleHDADisabler.kext to System/Library/Extensions using Kext Wizard or another kext installer of your choice.

This is the most update proof solution I've found.
