Okey, after your post I did some more research what I need to do for my MB to work and hoped you could help me to correct the thinks I understanding wrong.

kext needed:
LegacyHDA.kext - Helps fixing the HDEF audio
OpenHaltRestart.kext - Fixes restart/shutdown
fakesmc.kext - Some decryption thing for make the system work?
UUID.kext or PlatformUUID.kext - Removes the boot warning about UUID root device
smbios.plist - Make the System profiler display the right information (After editing)

DSDT patches:
HDEF(Audio) - Fixes the onboard 889a audio(HDEF), but LegacyHDA.kext still needed
Ethernet - Fixes the onboard network card
Time Machine - Fixes the 35 error?
Speedstep - Fixes the dynamic CPU speed scaling
ICH9-R - Fixes so the hard drives is displayed as ESB2
UHCI/EHCI - Fixes the USB port to they are displayed as onboard and work in "high-speed"
RTC/HPET - Fixes the out of sync clock when multiboot and remove the CMOS reset bug in
