The glue for binary ATI drivers did not even compile for me. The mesa library should support OpenGL 2.1 since version 7 but it seems that support for different features in hardware accelerated drivers varies per chipset due to hardware limitations or some features may be simply not implemented for some hardware. I would also think that higher level libraries like Ogre or CrystalSpace would make a better job at isolating the developer from these hardware and driver differences than raw OpenGL. > varies greatly for different models and from distro-to-distro.  I'd heard > that the Intel x3100 IGP and later chipsets were supposed to support OpenGL > 2.0+ but haven't had direct experience with them. > I don't have such system at hand either, only i945G/GM (something like GMA900 or GMA950) here.
