Really?!? I'm quiet sure I had i815 machines with working glx.
Is it possible that I had OpenGL in Xfree without FreeBSD DRM?
In 2002 I had lots of i810/815 machines supplied with FreeBSD 4.7 and I saw 
glxgears working at reasonable speed (according to the i810 capabilities).

Thanks for your attention!
