I found a way you could try that would let you do what you want without 
having to change anything in gdm (and on top of that, I would really say
this is the right way to do it as doing it in gdm would be really overkill)

What I did is change all my session scripts by a copy of the little 
shell script attached ( I did not do a link because I am scared that
gdm might have something against symbolic links).

What the script does is try to match the id of the session user with
an executable file located in

/usr/X11/gdm/Session/group/{gid}/{sessionname}

where {gid} is the group of user of the Session
and {sessionname} the name of the Session in the directory (e.g. Gnome, 
KDE, default)
If it cannot find something to execute there, it will try to execute
the default in  /usr/X11/gdm/Session/nogroup/{sessionname}

The script tries each id listed in 'id -G' and picks up the first one.
Up to you to provide corresponding sessions for the correct groups and
supply the directories & files (with +x bit set) in the directory 
/usr/X11/gdm/Session/group/ and nogroup for people without specific
profiles.

I believe this is the right approach for your problem.
If you need something more complicated, then it will be easier to
use a kind of database instead but you should try to see if this 
approach would not fit what you want.

I don't think changing GDM will gain you anything (George?)

cheers,

Guillaume
