Say you use kdm, which doesn't ship a native service file yet and
doesn't yet support the new scheme, you could try a different approach:
Add systemd.mask=kdm.service to the kernel command line

This will runtime mask the service and prohibit it's start.

Btw, when you boot with systemd.unit=multi-user.target, what is the
output of
systemctl status graphical.target multi-user.target

My gut feeling is, that it's actually a bug in the actual display
manager and should be re-assigned accordingly.
