It helps. I don't use Arch. Based on what I found there, I built this repair 
script:

# /bin/sh
  cp -a /usr/lib/systemd/system/getty at .service 
/usr/lib/systemd/system/getty at tty1.service
  sed -i 's/TTYVTDisallocate=yes/TTYVTDisallocate=no/' 
/usr/lib/systemd/system/getty at tty1.service
  ln -sf /usr/lib/systemd/system/getty at tty1.service 
/etc/systemd/system/getty.target.wants/getty at tty1.service
  systemctl start getty at tty1.service
  ln -sf /usr/lib/systemd/system/getty at .service 
/etc/systemd/system/getty.target.wants/getty at tty2.service
  systemctl start getty at tty2.service
  ln -sf /usr/lib/systemd/system/getty at .service 
/etc/systemd/system/getty.target.wants/getty at tty3.service
  systemctl start getty at tty3.service
  ln -sf /usr/lib/systemd/system/getty at .service 
/etc/systemd/system/getty.target.wants/getty at tty4.service
  systemctl start getty at tty4.service
  ln -sf /usr/lib/systemd/system/getty at .service 
/etc/systemd/system/getty.target.wants/getty at tty5.service
  systemctl start getty at tty5.service
  ln -sf /usr/lib/systemd/system/getty at .service 
/etc/systemd/system/getty.target.wants/getty at tty6.service
  systemctl start getty at tty6.service

In openSUSE 13.1 I get the result I want, first two X sessions opened goto 
vt7 & vt8. vt1 keeps its boot messages. Login prompts appear on vts 2,3,5,6, 
and the login on vt4 where I ran startx -- :1 is full of expected Xorg messages.

In Fedora 19 and Mageia 3, prompts get started on vts 1-6, KDM goes to vt7, 
but on vt4, where I login to run startx -- :1, is where the 2nd X session is 
found instead of as expected on vt8.
