hi Gringo
I use an Asus F3Jc T5500 laptop under 10.5.6 (retail Munky's method and Chameleon RC2)
EFI partition - KEXTS USED - AppleDecrypt, Disabler, SMBIOSResolver, HDAEnabler, OpenHaltrestart, ACPIBattery, VoodooPS2Controller, ClamshellDisplay, EHCISleepEnabler, VoodooPower, LegacyAppleAHCIPort, IOSDHCIBlockDevice
In S/L/E I have ALC861 for the sound and VoodooPS2Controller.kext and Efi string NVS_QE for my Go 7300 in the com.apple.boot.plist
Two days ago I added UUID.kext to the EFI/Extra/Extensions folder and EFI ethernet string to com.apple.boot.plist
Everything was fine to me excepte when I wanted to make a bootable copy of my system. Maybe one thing : repair permisions take a verry, verry long time, one hour.
Well, thank you again
