I ran into a similar problem a few months ago (probably closer to a year
ago now) with respect to GLX visuals on the client-side and on the
server-side. My solution was to use a new structure, _GLcontextModes,
to represent the data. The data provided by the driver in the old
structure was converted to the new structure by a device-independent layer.
