[Nouveau] Problem with GT520 and optimus on Fedora 17

[Gianluca Cecchi]

Hello,
I have an Asus laptop, U36SD, with Optimus technology.
The discrete gpu is an NVIDIA GeForce GT 520M with 1GB DDR3 VRAM
Using Fedora 17; up to kernel 3.3.7-1 I was able to use bumblebee and
bbswitch and then running optirun command (as I could do in F16).
No more with kernel 3.4. Tried 3.4.0-1.fc17.x86_64,
3.4.2-4.fc17.x86_64 and 3.4.3-1.fc17.x86_64.
I already opened a bug against F17:
https://bugzilla.redhat.com/show_bug.cgi?id=831136

I'm using
bbswitch-0.4.2.tar.gz
VirtualGL-2.3.1.x86_64.rpm
bumblebee-3.0.tar.gz
and nouveau kernel module

In dmesg output of 3.3.7 I see this:
