Thanks for your reply.
If systemd is found it gdm will be build with systemd.
Before recompiling (with systemd) gdm didn't have permission
to start, even by root.

In the meantime I found the solution (partial)

That is included by /etc/pam.d/gdm
But /etc/pam.d/gdm-launch-environment doesn't include
system-auth in it's session section. So I tried adding
that pam_systemd.so into gdm-launch-environment.
That works on one system using xorg's nv_drv.so.

But on the system with an Intel-videocard the first step
of gdm (the gnome-shell) results in an Oops-screen.
I can remember dat gdm-gnome-shell only had been
working in Gnome-3.0. I stopped working since 3.2, always
only starting fall-back mode.
I am almost certain that I can get gdm working there by 
uninstalling gnome-shell.
