Hi,
great it works. I now have a working stamina-speed switch and right now
I'm running on the Nvidia chip, with latest Nvidia drivers. I've done
nothiing else, than install a stock 11.04. When I boot with the switch
in stamina mode, I get the colorfull vertical lines, so I can't see the
Grub menu, but Ubuntu starts just fine.

"glxinfo | grep rendere" reports:
"OpenGL renderer string: GeForce 9300M GS/PCI/SSE2"
This has until now always reported the Intel chip....wuuuhuuu....

As others have reported, brightness buttons no longer work though.

My model is the Vaio VGN-Z21WN
