Might I suggest to both of you - I install these kexts to my boot stick after each successful install on my system, doing the same (My fix, or permissions repair) as I do on my system. That way, should something KP in a way that I can't undo by either booting in with the stick or single user, I have my backup. FYI iLife 11 and iWork 09 installed and updated without a problem (some of the iLife programs took a little while initializing however). By the way, Tengokuu, which bootpack are you using on your system - the M4300 or Mariusz? The SleepEnabler.kext caused KP on my system.
