Bug#718774: Nvidia module rename patch break bumblebee

[LOMBARD Maxime]

To launch glxgears with Intel card correctly, i must to re-install mesa-glx
and nvidia-glx (I launch this command with Nvidia 304.88 and it works) :

> aptitude reinstall libgl1-mesa-glx libgl1-mesa-glx:i386 libgl1-nvidia-glx
> libgl1-nvidia-glx:i386 bumblebee-nvidia
>

So now, if i launch "update-alternatives --config glx", i have this result :

> It exist 2 choices for alternative glx (which supplies /usr/lib/glx).

For "primusrun glxgears", i have this :
