I think that bit in the ARB_sync spec is incorrect.  I believe the extension is
written against the OpenGL 3.1 spec, but I don't believe that 3.1 is actually
required.  As Tobias mentions in comment #2, we implement this extension in the
i965 driver without any problems.  We didn't encounter any odd interactions or
dependencies along the way.
