edited post: I sucessfully removed the intelenhancedspeedstep, but I really wanted it I just installed it with kexthelper and well no dice, I got a question do I have to remove the appleintelpowermanagement first before I install this and well if I do and the intelenhancedspeedstep still doesn't let it boot how do I recover?

To remove use terminal

CODE

sudo -s
rm -Rf /System/Library/Extensions/AppleIntelCPUPowerManagement.kext

To back it up

CODE

sudo -s
cp -R /System/Library/Extensions/AppleIntelCPUPowerManagement.kext /Path/To/Backup/Folder

To recover it use the same kext helper, just install the kext from the backup. Or via terminal

CODE

sudo -s
cp -R /Path/To/Backup/Folder/AppleIntelCPUPowerManagement.kext /System/Library/Extensions/AppleIntelCPUPowerManagement.kext
chmod -R 644 /System/Library/Extensions/AppleIntelCPUPowerManagement.kext
chown -R root:wheel /System/Library/Extensions/AppleIntelCPUPowerManagement.kext
rm -Rf /System/Library/Extensions.mkext

Note that if you unable to boot the system and use an install DVD or the other OS X installation to recover, paths to files will be different. Add /Volumes/TheDiskOSXisInstalledTo
