[OM Cooker] Use modesetting driver instead of intel and nouveau

Ok I have tested the modesetting driver and it seems to work fine on my NVidia kit.
I ran glxgears -fullscreen and got 60 FPS the same test with the nouveau driver gave 36 FPS.
It's definately better performing.
During the tests I typed reboot from a root terminal a number of times and there 
was always a kernel crash irrespective of which driver was being used.
There's a screenshot here:-  https://drive.google.com/file/d/0B0qGV0eSLYwHb0VQODI4MV91djVIR2RQclFCYmFROWRYSVpV/view?usp=sharing
I wonder if it's related to the nouveau.
Since no-one has a clue as to whats causing the nouveau bug I thought it might be 
worth someone more expert than me to take a look.
Best,
Colin
