The CPU usage of glxgears is not a good indicator of whether your GPU is 
in use. I get 97% usage on my GeForce 6800GS which I *know* is correctly 
configured (try running Doom 3 without GPU acceleration :) )

glxgears uses so little of the GPU's power that it's mostly CPU-bound 
anyway.

If you want to find out whether your GPU is being used, run

$ glxinfo | grep direct
direct rendering: Yes

If it says "direct rendering: No" then you need to work on the 
configuration. If it says "Yes" you should be fine.
