This solution for now is ok on my laptop (Asus A6T, Kubuntu 6.06).
The flag as to be set every time the computer is started, but i thing that is possible to change also the xorg.conf.
I hope that this solution can help also to correct the problem on the next driver release.
To made permanent this flag, according to the nvidia readme, i've set the Environment Variable __GL_FORCE_GENERIC_CPU to "1" (modified /etc/enviroment).
The variable is present (computer restarted and verified with "export"), but I need also to change everytime the Nvidia X server settings.
Where I can set permanent this change (or the variable is incorrect) ?
