Given that the performance with nv, as you noted, is much better than
with your card, I would strongly suspect your issue is a bug in the
nvidia driver, and perhaps in the X server also. (I am aware that 
other people with proper hardware acceleration have been using this 
code for quite a while.)

That said, the presence and type of anti-aliasing may become
configurable in future versions of the OpenGL renderer.
