HI, I followed the steps and I have successfully installed 10.8.2 . Everything works. (however, I had to swap out the wifi card for a apple compatible "broadcom chipset" to get wifi, It was easier to get one on ebay for 10 bucks. It' worth it., i even got 5g to work.
Like I said everything works. Sleep works too, "after the terminal command" as instructed,
however the shut down does not work properly. Sometime I shuts down ok, but other times mostly. by button or command clink. (which ever)
and it hangs for a little , (grey screen), and starts at the login screen and does not shut down. I have to hold the power button
to force it.
anyone found a solution for this? its a little annoying.
Thanks
