That doesn't make any sense to me -- all previous versions of the NVIDIA
drivers would have diverted your glx module to one that only worked with
NVIDIA.  Nothing changed about the latest version in that regard.

Which is exactly the same thing that would have happened with nvidia-glx
in any previous version of the package.

There has *never* been a way to select MESA if the NVIDIA packages are
installed.  Previous versions used diversions.  The current version is now
introducing alternatives so that eventually there will be a way to install
both packages and select MESA, but that has never previously been possible
and is not yet possible.
