Enabling sli

[Plosky]

I am trying to configure a sli setup for both of my 6600gt Nvidia graphic cards but I am experiencing some troubles. Of course, I enabled the Sli option in my Xorg.conf file but I think the roblem resides in the pci bridge. Personnaly I believe that the pci bus brigde is not well recognised because of the output of the following commands. Any help to further analyse my situation would be greatly appreciated. Enabling double gpu is the only thing stopping me from totally removing windows of my system.

Thank you for your consideration

The following commands had this output :
