I had the same problem on my labtop with ATI Radeon M9. Tried everything that 
is suggested in various postlist and nothing worked. Then I found this page  
http://www.gmpf.de/english/ and followed it's instuctions and voila!  no more 
"Xlib: extension "GLX" missing on display ":0.0" but a working 3D OpenGL. :). 

All I had to change was <Option "UseInternalAGPGART" "yes"> to <Option 
"UseInternalAGPGART" "No"> and restart X.

Hope this helps.

Arnar
