[PD] many DVI ports with Debian/Ubuntu and Gem

The screens we are currently specing are 1080p, so each output should  
be able to do 1080.  The idea is to have 10 contiguous screens all in  
a line show one Gem space.  They can show up on the computer as  
contiguous or separate screens, that doesn't matter, I can handle the  
difference in Gem.  I think it might be easier to have them show up as  
separate screens.

I can break it up across multiple computers if that's easier, I'm  
mostly trying to reduce the expense.  I am just showing images, so not  
heavy on the CPU/GPU.
