Hey guys,

I think I must be pushing my luck, I decided to install bumblebee today: 
https://github.com/Bumblebee-Project/Bumblebee/
Rebooted with the switch in 'auto' position.
Upon booting, I checked power usuage:

"The battery reports a discharge rate of 11.6 W"

Ran glxspheres:

csb@csb-laptop:~$ glxspheres
Polygons in scene: 62464
Visual ID of window: 0x92
Context is Direct
OpenGL Renderer: Mesa DRI Intel(R) Ironlake Mobile
20.078867 frames/sec - 22.408016 Mpixels/sec
26.432012 frames/sec - 29.498126 Mpixels/sec
29.906124 frames/sec - 33.375235 Mpixels/sec
28.067554 frames/sec - 31.323390 Mpixels/sec


Now for the real test:
csb@csb-laptop:~$ optirun glxspheres
Polygons in scene: 62464
Visual ID of window: 0x21
Context is Direct
OpenGL Renderer: GeForce GT 330M/PCIe/SSE2
74.902735 frames/sec - 83.591453 Mpixels/sec
127.273131 frames/sec - 97.262626 Mpixels/sec
169.620041 frames/sec - 115.070236 Mpixels/sec
174.924951 frames/sec - 118.669087 Mpixels/sec
166.887317 frames/sec - 113.216356 Mpixels/sec
171.806394 frames/sec - 116.553458 Mpixels/sec
167.313173 frames/sec - 113.505256 Mpixels/sec


That will do me!

Just modify the launcher of any application that needs the GPU to use 
'optirun'.

Hope this works for you.

Craig
