netkas.org has instructions on how to flash the 1,1 board to 2,1. It's the same board exactly. it takes 4gb of ram (3.3 usable) but matched pairs go faster with GMA950 and core2duo is supported with 2,1 plus there are 2,1 keyboard features that work with the flashed board. The only issue is the o/s will see the nvram code that says its a 1,1 board but this can be circumvented using common hackintosh methods.
I don't understand why mountain lion can't emulate the video, when say windows 8 will run on the same hardware! damn apple!
