      <title>Working around problems with the Intel driver</title>

      <para>
        The SandyBridge New Acceleration (SNA) code is intended to replace the
        old UXA (UMA Acceleration Architecture), but it is a large body of code
        and may cause problems.  However, the version of the code in the
        version control system listed above has been tested successfully with
        both SNA and UXA capabilities.
     </para>

      <para>
        To work around this problem, as well as enabling support for UXA, it is
        necessary to force UXA to be used by creating a configuration file.  If
        this problem applies to you, create the following file as the
        <systemitem class="username">root</systemitem> user and modify it as
        needed:
      </para>
