My guess
puppet
Why?
Because puppet can work on generalities.  You can say that you want the 
driver for your video card, and it can figure out the correct driver.

No, on this point you are wrong.
The dependancy is libGL.so.1, and *any* of the "provider" packages can 
supply that package.  It only has to install one of those packages.  If 
your repositories were just plain SL, it would be xorg-x11-Mesa-libGL. 
But since you have (it looks like) sl-contrib and dag enabled, it can 
pick whichever one it feels is right.
