Bug#718774: Nvidia module rename patch break bumblebee

[LOMBARD Maxime]

Hi Vincent,

1- I re-installed Debian Sid + Nvidia Experimental. Concerning
"nvidia-modprobe.conf, i have this :

> berillions at debian64:~$ cat /etc/nvidia/nvidia-modprobe.conf
> alias nvidia nvidia-current
>

2- Result of  "update-alternatives --config glx" before to re-install
"libgl1-mesa-glx" :

> root at debian64:/home/berillions# update-alternatives --config glx
> There is only a "alternative" in the group of links glx (which supplies
> /usr/lib/glx) : /usr/lib/nvidia
>

--> I tried to launch primusrun glxgears : "primus: fatal: Bumblebee daemon
reported: error: Could not load GPU driver"

3- Result after to re-install "libgl1-mesa-glx" :

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