I solved every KP doing exactly what the guide states, sans the part with permission fixing. so install everything and prepare all stuff, normally boot inside 64bit mode, dont do disk utility permission fixes but download the latest osx 86 tools software (google, its discontinued, but offers a gui for all the stuff you'd otherwise had to do on the terminal)
check the settings like that:
hit "Run selected tasks".
Done. No more KPs for me. Hope it helps. This procedure has to be done after every update, new program installation etc.. just to be sure the systems stays fresh
Cheers.
UPDATE: I forgot to mention.. if i disable the onboard lan cards, no KP ever happens. Obviously the IONetworkingFamily.kext corrupts the system in 64 bit mode, and screws 32 bit mode over when you fix its permissions with disk utility. my guess is that its the cause of the problems.
