Hi All, The crash problem with some rate combinations of Radeon hardware and drivers has been identified and eliminated. Thanks to everyone who responded.
This turned out to be an issue of the driver not completely flushing the OpenGL pipeline before returning pixels from the display buffer. The driver got confused and was bringing down the whole system as a result. The problem goes away if we manually flush the pipeline before issuing any glReadPixels calls. Thus, it is one again safe to buy Mobility Radeon 9000 hardware for use with PyMOL! (the latest beta has the patch http://delsci.com/beta ).
