This is brilliant. The first link noted above, to GMA950, downloads a little zipped installer file. I downloaded it, installed it, restarted, and then plugged in a VGA monitor. The monitor was immediately mirrored. The delay while starting the mirror was minor and momentarily caused me to worry, but after that it works as expected - even for video clips. My AAO becomes more Mac-like by the day. I did not search long through the second link noted above, having decided to just install the drivers... But thanks to Janjalani for bringing this to our attention, and to anyone else who helped make it possible. My specs: AAO 150 (120GB HD) with the OS X Atkos 4 install.
