Bug description:
  [Impact]
  AMD posts beta versions of their drivers to be tested over several weeks. 
These drivers usually include important features and fixes but also sometimes 
include known issues or regressions that make them unsuitable or too risky for 
us to consider inclusion in the fglrx-updates package.

  However certain commercial Linux games require features/fixes present
  only in these AMD beta drivers at the time of their release. Ubuntu
  users who purchase these games currently have to manually install the
  beta driver (or wait a month or two for it to appear in -updates).
  Providing these drivers via fglrx-experimental will enable them to
  install and run the game within the Ubuntu packaging system.

  [Fix]
  The fglrx-experimental-NNN binary package is established (provided by the 
fglrx-installer-experimental source package) for quantal 12.10 and precise 
12.04. This uses the packaging scripts from fglrx-updates, with the renamed 
package and new .run files.

  The fglrx-experimental-NNN package will be visible to users via Jockey
  as normal. When a user installs the experimental package, any other
  fglrx drivers will be disabled. They will remain on the selected
  fglrx-experimental-NNN until they upgrade to a new Ubuntu release or
  LTS point release, at which point they'll be returned to fglrx-
  current. They can of course manually switch from fglrx-experimental-
  NNN back to fglrx or fglrx-updates (or some newer fglrx-experimental-
  MMM) if they wish.

  The control file for the experimental package proposed for precise has
  some differences from the one in quantal, and also has some
  differences against the non-experimental fglrx driver in precise. Here
  is an explanation of those differences in turn:

  * Conflicts/Replaces on fglrx-*-modaliases (from precise's fglrx
  package) are no longer needed. The modaliases packages were used in
  previous releases but no longer exist in precise. Since people can't
  upgrade from those previous versions directly to fglrx*experimental,
  there is no need to have Conflicts/Replaces.

  * Conflicts/Replaces/Provides of various nvidia/fglrx packages (from
  quantal's fglrx-experimental package) are only needed for quantal
  forward. These are required by the new restricted drivers UI in
  quantal. Since that UI is not in precise, we don't need it in precise.

  [Regression Potential]
  The reason we're adding this package in the first place is because of 
concerns that beta drivers will have a high risk of regressions. Thus, users 
need to be aware they are taking these risks when they opt-in to the driver.

  As mentioned above, fglrx and fglrx-updates will still be available to
  them in case they have problems. In a worst case scenario they may
  need to do this from a recovery session.
