Looks like we need a separate profile for the glx alternative to support
bumblebee with the new nvidia driver configuration scheme.

Is the following correct for nvidia+bumblebee:

* the nvidia kernel module is available
* but it is *not* autoloaded
* nouveau is blacklisted
* Xorg is *not* configured to use nvidia_drv.so

With the mesa-diverted profile you use, the nvidia module is *not*
available any more (i.e. known to modprobe as 'nvidia' - therefore
modprobe -r does not work) and nouveau is not blacklisted (unless
bumblebee comes with its own blacklist).
