Default basemosaic linux

I've been attempting to get basemosaic to work on my system, I currently run 6 monitors off of 3 identical 9500GT cards.
I modified my xorg.conf to use this line.
Code:
 Option         "BaseMosaic" "True"
Option         "MetaModes" "GPU-0.DFP-0: 1680x1050+0+0, GPU-0.DFP-1: 1680x1050+0+1050, GPU-1.DFP-0: 1680x1050+1680+1050, GPU-1.DFP-1: 1680x1050+1680+0, GPU-3.DPF-0: 1680
x1050+3360+0, GPU-3.DPF-1: 1680x1050+3360+1050"
This sortof worked, my first 4 monitors (off of GPU-0 and GPU-1) worked, however monitors 4-5 stayed blank.

I got this in my log
Code:
[    20.350] (WW) NVIDIA(0): Invalid display device in Mode Description

[    20.351] (II) NVIDIA(0): Virtual screen size determined to be 3360 x 2100

It is recognizing the gpu3 existing and even correctly detecting my monitors (not in the snippit above) , but then says it can't use it in basemosaic.

Is this a limitation of basemosaic? only 2 GPU's? or is this a limitation of the fact that the 3 cards I have are not a valid SLI configuration (they're only single SLI, thus I can't SLI them together) or something else entirely. I was unable to find any significant documentation outside of the readme, which seemed rather terse.

Any help would be appreciated.
