2) second way, old good way with startupfiletool

create Dirrectory iamefi in root of your boot osx disk
and copy all files from unpacked achieve to it
boot to single user mode (press f8 durring boot(after bios booted) type -s and press enter)
then make next commands
cd /iamefi
./startupfiletool /dev/rdiskXsX ./boot|_v4
and reboot

existing 10.4.10 and 10.5 kernels, compiled from sources, made by Toh are already ready to work with this pkg

u also can use vanila appleacpiplatform.kext for leopard, and vanillas applesmbios.kext, but better to install
applesmbios.kext from this pkg, to fix things like System profiler and cpu speed. or u can still use applesmbios from netkas.
for vanilla kernel u have to use dsmos.kext also
What's advantages of it all ? 
U can run stock apple kernel on C2D(e6xxx, e4xxx, e21x0), C2Q, celeron 420, CD, CS and intel mobo.
And geekbench2 detects u as mac, not a hack.
