Thanks for the reply. When I run the Nouveau driver, I get the Gnome "fallback" version. And I see a console message that says that there is no 3D hardware acceleration. I've got the same software versions.
You mentioned that you have a GeForce 7300 card. All GeForce 7300 (GT,GS,LE,SE and PCIe or AGP) cards have "3D hardware acceleration". They should be recognized as such when booting F15. What does 'lspci -d 10de:' say.
You are running the Nvidia driver. This requires a 'nomodeset' entry in the kernel line of /boot/grub/grub.conf (if I remember correctly). To switch to the nouveau driver you have to disable the nvidia driver. Have you checked if the 'nomodeset' entry has been removed.
Also have a look at system settings->system info->graphics->forced fallback mode->on/off
