1.1 deraadt 348: The 2.9 CD cover states that XFree86 3.3.6-current is included. This is only half-true.
349: In fact, the XFree86 included for all architectures is 4.0.3. On the i386, the
350: 3.3.6 Xservers have also been included, because 4.0.3 still has weak support for
351: some devices which 3.3.6 supported better.
