Ray (who wrote most of this code) is busy doing something else right
now, so let me summarize what I know about this:

What gdm does it is only shows a language in the list if a) we have
translations for it and b) we have fonts for it. For b), we basically
ask fontconfig "do you have fonts for this language ?". It seems that 
fontconfig says "no" if it doesn't know the language. It would be better
if fontconfig could say "I don't know" in that case...
