Good, erasing or reduce mode access to /var/log/ConsoleKit/history might 
be a workaround .

In the mean time I found this from 
http://library.gnome.org/admin/gdm/stable/overview.html
"The Face Browser is the interface which allows users to select their 
username by clicking on an image. This feature can be enabled or 
disabled via the /apps/gdm/simple-greeter/disable_user_list GConf key 
and is on by default. "

Then I tried to set that "key" (disable_user_list) with gconf-editor 
with no sucess :-(
here's a possible patch, but I haven't tried yet

%changelog
+* Thu May  8 2008 Matthias Clasen <mclasen redhat com> - 1:2.22.0-6
+- Add a GConf key to disable the user list

If someone succeed in setting "disable_user_list" please let us know .
