Indeed no, since they both are providers for the GL stuff, and we can
have only one provider for each virtual package.

This series is surely not exhaustive about GL dependencies. My test-case
was to build Kodi for my HTPC (NVidia GPU, as you may have guessed!),
and that series makes it at least build (I still need to extensively
run-test it, though), so it is very well possible that building X.org
for NVidia-based accelerated X is not working completely (but that would
be an new feature, not a breaking of existing features).

I see you have submitted the patches already. Thanks for working on
that! :-) I'll have a look at them.
