ACPI_SMC_PLatformplugin

[fc bayern]

I' ve been isntaling SL for over a week
I've been folowing dozens of guide's(to install SL from Leopard, pure vanila instalation, etc), but Always get this anoying messages, and the SL hangs up here
I've tried deleting AppleSMC.kext, but no success.
I'm running Iatkos 10.5.7, updated 10.5.8
I'm going crazy, i think i'll be giving up on getiing SL
