I reinstalled Oneiric Alpha3 on one Arrandale system (Toshiba Tecra A11) to try and reproduce the original problem. It does occur exactly as originally described, with the primary display showing a "dead area" on the top 1/3 of the screen, and the secondary display being black except for the top panel.
I'm currently installing from latest image (20110906) to try and reproduce the compiz crash and file about that, if needed.
