Hi there, Ju!
I was able to get snow leopard 10.6.8 working (more or less).
The WIFI is a lost case, we are going to have to buy a dw 1397 or a dw 1510 on ebay to have wireless on our boards.
But the ethernet its a different story
I got it working with the next kext on S/L/E:

I downloaded the DSDT that MaLd0n compiled , 'cause I have the same system as you. (Thanks, MaLd0n!!!)
I have not been able to get the trackpad working (ALPS)
Hope things get better!
