[Impact]
 * Installing packages that require opengl dev libraries can cause the renamed stack to be uninstalled.

[Test Case]
 * sudo apt-get install xserver-xorg-lts-quantal
 * sudo apt-get install libqt4-opengl-dev
 * Watch the suggested resolution being to go back to the unrenamed xserver, deleting all lts-quantal packages.

[Regression Potential]
 * Low, mostly it ends up being a rebuild of mesa
 * Unrenamed mesa-dev packages will work on the new stack, which is an untested combination,
   however the relevant packages are backwards compatible, and the abi will not change. The
   worst that can happen is not finding new opengl extensions.

[Other Info]
  * Important for 12.04.2
