Thanks for your update to this great guide, new files worked fine.

I wonder, what is the purpose of making your own mkext file? I don't have one on my EFI partition, would it make the boot time shorter if I had?

Another thing I discovered just now is that I can't boot into 32bit. I never tried before but I was trying to get final cut going and thought it might help with 32bit. I'm getting a KP quickly into the boot.

I tried the fix in this thread : http://www.insanelymac.com/forum/ind...owtopic=181209 but no luck.
Also I'm not sure if I should include the kexts in the EFI partition when rebuilding the mkext as the fix says.

Fixed: Writing this in 32 kernel. I moved my installation from efi partition to main partition, but I think the problem was that some of my kexts had root:admin ownership instead of root:wheel. It was kextcache that complained about it and gave me the clue. I guess the fix in the thread above is quite good after all.
