Here are the kernel extensions I’m using on my ASUS P6T (non SE, non Deluxe) mainboard to run Mac OS X 10.6. I’m not planning to write a guide for a vanilla installation but I already summed up some important points when installing OS X on the P6T in this post from a retail Mac OS DVD.

With these kexts, my P6T with 12 GB of 1600 MHz triple channel RAM, a Nvidia GTX 260 graphics card and several SATA drives runs rock solid, including on-board sound, support for multicast networking (important for Bonjour), sleep and waking up just by touching my wireless USB mouse. I’m even able to overclock the i7 920 to 4 GHz and it still runs stable. I have a monstrous CPU cooler mounted though. Running at 4 GHz, the ASUS P6T with the Intel i7 920 CPU achieves a Geekbench score of 12400 points.
