Exclamation Fedora 17 x64 3 monitor setup

At home I have Fedora 17 x64 running with 3 monitors using the BaseMosaic option.
Gnome works perfectly ( Not fallback mode )
2 x 460GTX's
xorg.conf at home
Code:

At work I have tried the same configuration with the GPU/DFP setting modified for the screens at work and It is not working, I only get one monitor. I have put in what I think is relevant info below.

Note:
I can get 3 monitors running with xinerama and gnome fallback mode with the 550's. With the BaseMosaic setting at work I get 1 monitor
At work I am running 2 x GTX 550 ti

Work xorg and gpu-info
