maybe not what you want and maybe of some usefullness...

In the xorg.conf you can put

Section "Device"
     Identifier     "Device0"
     Driver         "nvidia"
     BusID          "PCI:07:00:00"
     Option         "UseDisplayDevice" "none"
     VendorName     "NVIDIA Corporation"
EndSection

I always had to start an xserver (if you have more than 1 GPU you can add 
device and screen sections has needed to xorg.conf). I've been using this 
to render using Tesla cards.

Off course this needs to start X...

best,
