No rotation option

Attached is the updated system profile after doing what you said.

I've rotated the monitor before on leopard and have never had any compatibility issues with the 1706 until I upgraded to a mac pro.

Well the profile looks better now but no hints about the rotation issue, I'm sorry.
Actually I just remembered that I've seen the same issue once on a first generation MacBook Pro. Problem was, the rotation drop down disappeared from the screen connected to the DVI port as well.
I tried everything, starting from uninstalling our driver of course but without any success. I had to reinstall the OS (easy with 10.6 fortunately) to restore the rotation.
If you can't rotate the other screens as well then this might be the solution. If you can rotate them I don't think it's worth trying the reinstall.
