    Thanks for the info. You're right the newer versions of xorg have the multihead support fixed (sort of).
I installed Ubuntu 10 alpha 2. Only two screens came up on auto configure but Xorg -configure generated a working xorg.conf with both chips. 

Now a new issue has appeared. The two heads on the primary interface flash periodically. I remember reading another post somewhere about this issue.
