Yes, that's the demo I was referring to.  It works for me with Mesa
3.4 and 3.5.  I haven't tested with any earlier version of Mesa but
I'd be surprised if it didn't work.

I'm testing with software rendering using the glut included with Mesa.
I'm using a generic PIII system with RedHat 6.2 (which really is
irrelevant).

I see that you're using Utah-GLX.  I have no idea if the Utah
G400 driver supports stippled lines.  You'll have to ask them.
