I upgraded to FC 16 from 15. When I try to run GNOME desktop I get put into fallback mode. GNOME 3 worked fine for me on 15. The only difference is that I was using ATI Catalyst 11.10 driver. For 16 I am using the os distribution driver. Is this the reason I see fallback mode? If so, is there anything I can do to get it working short of waiting for the FC16 Catalyst driver?

For day to day use of the shell you could try the updated packages in rawhide which allow gnome-shell to run even on hardware without a native 3D driver. I have installed these packages on my 410M which is currently unsupported by the nouveau driver and have found it works quite well, your mileage may vary.

The original post detailing these changes is here:

To try this you need to do the following as root:

# yum install fedora-release-rawhide
# yum update --enablerepo=rawhide mesa-* cogl gnome-session

Note of course that installing the fedora-release-rawhide package only adds the repo as a potential source of software, it does not mean you are automatically running rawhide. By default it is still disabled which is why the --enablerepo option is needed on the second command as we only want to grab a specific set of packages (and their dependencies).

Asking when you can expect to see the graphics driver in Fedora supporting 3D, and therefore GNOME 3, on an ATI card is a very generic a question. The driver is known to support these things on many ATI cards. I would suggest obtaining the actual model information and checking the appropriate page(s) under the upstream project:

Yes, that probably is the reason. iirc, there isn't a driver available for ATI on f16 yet but you might want to head to #rpmfusion on the IRC and confirm once.

dmesg only shows a segment fault for rhythmbox.

I have uninstalled the Catalyst driver so I am not expecting any issues, nor do I see any --even rhythmnbox runs ok. But I am just not clear whether I can expect the distribution graphics driver to support GNOME 3 using an ATI card. I don't see anything obvious in ~/.xsession-errors so I don't know what could be wrong.
