The current driver relies on the BIOS to do the modesetting. So if the
BIOS knows how to drive the ADD2 card, then all is well. But use caution
here. It may drive the first digital port, but not the second on some
ADD2 cards. The new modesetting branch in the git repo is the driving
force to remove the BIOS from this equation though.

As for 3D accelerated on dual heads, yes, that's supported via MergedFB.

But rotation is not currently supported for G965 I'm afraid. Only the
945GM and older.
