Juan Nushio Rodriguez got sick of the Gnome Shell too and set out to bring back some sanity. See http://k3rnel.net/tag/bluebubble/
Q: What exactly is BlueBubble?
A: Its an effort to bring back the Gnome 2.32 desktop in Fedora 15, or as Hannah would put it.. The best of both worlds.
I have used the repository since June, apart from some small problems uninstalling gnome 3 (due to some legacy packages, fixed with forced rpm uninstalls) it has been smooth sailing. Yum complains about package dependency problems, but as explained in the installation instructions, you use "--skip-broken" and ignore them.
