Hello,

on RHEL6, to allow KDM to "see" the KDE3/TDE session type, I have to 
copy the file:
   /opt/trinity/share/apps/kdm/sessions/kde.desktop
to the directory where DM sessions are located, in my case:
   /usr/share/xsessions/

I supposo that you must to the same on Gentoo (except that your DM 
session directory is different).

Also, to run trinity without any DM, from a text virtual terminal, you 
can try, for example, the following command:
   xinit /opt/trinity/bin/startkde -- :1

This can help you to diagnose TDE session startup problem.
