Hi,
unfortunately I didn't have time to analyze and bisect with Fedora
kernels, but I did try all the new kernel released.
And I can say that finally today the 3.5.0-2.fc17.x86_64 is the first
kernel after
kernel-3.3.7-1.fc17.x86_64 where I can use my Nvidia again and run the command
sudo optirun glxgears
without errors.
Also, the discrete card is correctly disabled after optirun exits.
More tests to come

Thanks (possibly due to upstream changes in 3.5...)
