Confused about ACPICPUThrottle

[Invisible Ink]

I tried ACPICPUThrotthe.kest in its debug version following the instructions; from root terminal typed:

 

chmod -R 755 ACPICPUThrottle.kext

chown -R root:wheel ACPICPUThrottle.kext

kextload ACPICPUThrottle.kext

My CPU fan stops (slows down ...). Everything seems to work great and I found the extension loaded (I checked in system Info - Extensions)

Then I did the following:

 

- got the non-debug version

- copied in Sistem/Library/Extension

- added:

<key>OSBundleRequired</key>

<string>Root</string>

to Info.plist to force loading at startup (see: http://developer.apple.com/documentation/Darwin/Conceptual/KEXTConcept/KEXTConceptLoading/loading_kexts.html)

- deleted "Extensions.kextcache" and "Extensions.mkext" from System/Library to force rebuilding of extensions list of kernel

- rebooted

 

The extension didn't load at startup and the fan spins fast

 

Any suggestion?
