@scouse, as milanca has said below, i cannot get the wifi working at all and it will not work unless i get a new adapter. The audio on the other hand does work. I used the VoodooHDA.kext. This is available from:

Good luck

@milanca: Hi, thanks for your reply. Guess i'll just have to wait for Snow Leopard to see if I ever get my lan working . For my graphics, i have already tried the efi string method using efi studio, without any injectors and the latest stock kexts. Also tried doing this and adding my device ID to nvdaresman.kext and nvdahal50.kext. Every thing just boots up into OS X with a black screen. Ive tried turning my screen brightness up, plugging in an external monitor, opening and closing the lid and pressing the power button. It is not in standby, it just seems to be stopping when it needs to display the graphics. I think that it is probably displaying it in qe/ci behind this black screen but something is wrong somewhere. Anyone have any ideas?

Thanks for your time
