I tried using:
glHint( GL_POINT_SMOOTH_HINT, GL_NICEST );
It didn't make any difference on the nVidia GeForce 2 card.
You may be right about not being able to do round points in hardware.
You need two additional calls to enable smoothing and alpha blending.
The smoothing filter produces only correct alpha values.
Use the following code sequence to draw "round" points.
glEnable (GL_POINT_SMOOTH) ;
glEnable (GL_BLEND) ;
glBlendFunc (GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA) ;
glBegin(GL_POINTS) ;
...
glEnd() ;
