Laptop with vga external dual-monitors configuration issue


I am trying to span the display across 2 external 17" monitors connected via VGA y-splitter to my laptop. Currently it will only output the same thing to all 3 monitors (laptop-lcd, external-lcd#1, external-lcd#2).

Is there a way to treat both external LCDs as a single LCD and change the resolution on it to span across both LCDs?
-or-
Do I need an external 2nd video card to make this work?

Additional Information:
I am using the standard free nouveau driver included in the install, not the propritary Nvidia driver. The video card is a NVIDIA Quadro NVS 140M.

Code:
# xrandr 
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
LVDS-1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 304mm x 190mm
   1440x900       60.1 +   49.9  
   1152x864       60.0  
   1024x768       59.9* 
   800x600        59.9  
   640x480        59.4  
   720x400        59.6  
   640x400        60.0  
   640x350        59.8  
VGA-1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1024x768       60.0* 
   800x600        60.3     56.2  
   848x480        60.0  
   640x480        59.9  
DVI-D-1 disconnected (normal left inverted right x axis y axis)
I have gone through posts for similar issues but was unable to find information for this specific issue.

Thank you in advance for your help!

For some reason I didn't think to search the nVidia website, Thanks very much for guiding me in the right direction!

Unfortunatly I just recovered my system from a failed nVidia driver install(going on direction from another forum) and I will try again after backing-up & I'll report back with hopefully successful results.

Thanks again GlennsPref!
Don
