Installed a fresh Debian Wheezy to enjoy Gnome 3 but it starts in fallback mode. I suppose that's because the loaded drivers do not support 3D acceleration.
Installed packages I know are relevant:
The Gnome 3 was working fine with Ubuntu 12.04, and I belive it was using the FOSS drivers.
Interestingly there is no
/etc/X11/xorg.conf and when I try to generate it with
Xorg -configure I get:

I found now at the message boot:
