Subject: * A quick hack to get accelerated OpenGL working: just use the driver
   in /usr/lib/libGL.so.1 (which will typically load a driver in  
 /usr/X11R6/lib/modules/dri).  This has been tested on a i915   graphics card;
 it should work with most open source X.org drivers.   For NVidia's
 proprietary drivers (which we cannot build ourselves   anyway), some more
 symlinks are necessary; I'll add those later.

  So to get hardware-accelerated Quake 3, do:

  $ nix-env -p /nix/var/nix/profiles/opengl -i xorg-sys-opengl
  $ nix-env -i quake3-demo
  $ quake3
