Great!  One way to do this without a rebuild is to call
ImmediateModeRenderingOn() on all the mappers.  This should turn off
display lists.

Yes, according to Hank Childs the problem is with display lists.  the
else block after the if condition is called if the mapper is using
display lists.  If the Mesa folks want to see the OpenGLPolyDataMapper
code please do let us know.
