how to get "gnome classic with compiz" as boot session option?

Just got TC2 to install correctly on macbook pro. Details here:

On my older F16 installs, there was a boot option to use the GNOME3
compat session. However, in the newer images this is no longer an
option.

I see that on ubuntu one can install gnome-session-fallback to get this
option. (FWICT). What's the equivalent on Fedora? 

Or, how do I get "gnome classic with compiz" as a session option on F16?
