Thanks, voodoohda.kext worked! I had to put it in system\library\extensions as it doesn't work from efi or boot partition, right?
Also in system profiler it shows "no audio buit in", although I do get sound. Should it be like this?

I fixed the firewire by removing applehpet.kext!!

Also I used "empty_skull_x19x0_series 10.5.6" collection of kexts and plugins by putting it in the extras folder of my boot partition. I did this before I saw your post, but I will look into natit for future reference.

Thanks again
