Oh, one more interesting piece of information.. 

If I boot (power-on) the laptop *without* DVI cable connected, the nouveau
connectors will show up in 'xrandr' output as DP-1, DP-2 and DP-3. 

Now If i boot (power-on) the laptop *with* DVI cable connected, the nouveau
connectors will *NOT* show up in 'xrandr' most of the times, but during that
maybe one time out of ten when they do show up in 'xrandr', they're actually
called DisplayPort-0, DisplayPort-1 and DisplayPort-2. 

I wonder why that difference.. and if it's related to the issue I'm having or
not. I'm only able to hit the nouveau kernel crash when the connectors are
called DisplayPort-X, it seems. When the connectors are called DP-X, I'm not
able to crash the kernel.
