try changing your system definition to iMac 12,2 and enabling your internal graphics card (HD4000 if you have i3,i5,i7etc) as 'always on' in your bios. I did both of these and it is now working on my hack even using the AMD Radeon 6870 i have installed.
This isn't working here, with a 6850 installed on an i5-2500k with the integrated set to Always On.
EDIT: Got it working, you must set the Init First settings in the BIOS to the Integrated chip. Then, you lose visuals until you actually hit the desktop, which is going to make booting between OS's difficult, and changing BIOS settings a PITA. Other than that, its working correctly, though now my 889 sound takes 2-3 seconds to kick in whenever I attempt to use it if I haven't played audio in the last minute or so, making alert sounds useless (by the time the sound has kicked on, the sound has played already.)
EDIT2: Scratch that, the icon appears, my AppleTV is listed, but when I select it, the TV goes black, the Airplay icon in OS X turns blue for about 30 seconds, then it cuts itself off. No mirroring at all.
LAST EDIT I HOPE: After a reboot or two, it works correctly. I get mirroring and audio working as advertised, but I've still got the audio cutting out issue, along with the fact that I can't do anything with my machine until I get to the desktop. I'm thinking I'll hook up my display's VGA port to the on-board and just switch like that.
