I had to swop the WIFI card but that was only £6 and took 2mins to do.
Only probs I know of now are the brightness buttons don't work but you can change it in preferences and for some reason the trackpad won work if you use "UseKernelcache=Yes" Trackpad also only works as a mouse, no gestures.
Huge thanks to all the people who have written guides, made kexts and boot loaders etc.
A special HUGE thanks to artur-pt for patching the DSDT.
I hope these files help someone get theirs up and running quicker than the three weeks it took me.
:EDIT: I was a little hasty posting up those files as there are two more kexts needed that I only realised after doing a nice fresh install, I have also tweaked the the boot.com file.
I will shortly organise the files and re-post.
:EDIT I have replaced the attached file with one that contains all the kexts that need to go in S/L/E and the Extra folder to go on the / partition this was posted @ 22.14pm on Friday 15th March 2013.
If you downloaded the file before then please download it again.
