Need help with installing Mac OS X 10.8 on a Latitude D620 (Core 2 Duo/Intel Graphics)

I found a tutorial but the links leading to the bootpacks (I'm using myHack) are dead. I found another one, but for Snow Leopard and for a different CPU (Core Duo, not a Core 2 Duo) and GPU (Nvidia). Could anyone point me in the right direction?
