Xorg/Nouveau crashes with Segmentation fault when setting i7-Skylake iGPU as
primary grapics device in BIOS

Hardware:
CPU: i7-6700k (Intel HD Graphics 530)
MB: Asus H110M2 D3
GPU: NVIDIA GeForce GTX 750ti

How to reproduce:
- Install fresh Ubuntu Gnome 15.10 (Side note, graphic issues with standard
drivers, goes away with NVIDIA drivers so no big problem there)
- Install Kernel 4.3.4
- Install Intel drivers / compile and install latest Intel drivers
- Reboot
- iGPU isn't recognized as VGA compatible card
- Reboot and set primary graphics device to 'CPU Graphics' in BIOS
--> iGPU now is recognized
--> Xorg lives for approx. 1-2 seconds and then crashes

Xorg Version: X.Org X Server 1.17.2
