restricted drivers description needs update

Binary package hint: ubuntu-docs

Jockey's UI workflow changed in Intrepid, so the help for it needs to be updated. Proposed changes:

Using a restricted driver:
  1. Find the driver which you would like to activate in the list, and click on it.

  2. Read the description and license status to ensure it will do what you expect.

  3. Press "Activate".

  4. The restricted driver may have to be downloaded and gets installed, and your system configuration will be updated to use it.

  5. Some drivers require a restart of the computer to work. This is indicated in the status line of the driver.

Stop using a restricted driver:

If a restricted driver is causing problems, or you would just like to turn it off, follow the procedure below:

  1. Find the driver which you would like to deactivate in the list, and click on it.

  2. Press "Deactivate".

  3. The driver gets removed from your system, and your system configuration will be updated to use a free driver again, if one is available.

  4. Some drivers require a restart of the computer to become fully disabled. This is indicated in the status line of the driver.
