Currently users using gdm do not have option to choose classic Gnome session from the list of sessions (since 2.91, default gnome-session launches gnome-shell+mutter).
Session name is called gnome-fallback now.
Upstream doesn't want this, since it's a fallback session and is automatically run if gnome-shell cannot be run. I'm not sure if we want to include this.
I really want it :-P
(I am a bit tired of some upstream guys wanting to "force" people to use what they want...)

There's currently a setting to always run the fallback session:
Control Center > System Info > Graphics > Forced Fallback Mode
Also, don't expect fallback mode to be GNOME 2; it really isn't. It's literally a fallback from GNOME Shell. This is also why we'll be keeping GNOME 2 around for at least a year.
Well, I expect it to be a way of running Gnome3 without 3D acceleration (or a really poor and unstable one, that is the case) ;-)
For that I would prefer to be able to choose it before login in anyway

It seems I forgot to mention that there is a helper utility to check if 3D acceleration is present and usable. What you want should already work automatically.
The problem is that 3D support in ATI 9200 looks to work (I mean, glxgears "runs" even slow, some basic games like etracer works but it tends to make X crash, specially at logout, also make sometimes to get consoles lost...).
Maybe other option would be to document in out Gnome 3 upgrade guide about how to set "Forced Fallback Mode" for all users from command line with the gconftool-2 replacement (if possible).
Changing summary to reflect the current status:
* We won't be providing a separate session called gnome-fallback
* gnome-session automatically detects if your drivers/hardware is sufficient to run gnome-shell and falls back to gnome-fallback if required
* Users can force the fallback session to always be used by either:
System Settings > System Info > Graphics > Forced Fallback Mode
gsettings set org.gnome.desktop.session session-name gnome-fallback
We need to document this so that people can change to fallback mode from the console in corner cases of broken drivers, etc.
