If I may guess:
This sysctl refers to syscons (sc), while on FreeBSD 10 and
later, sc has been obsoleted by vt. Could that be the reason?
If you temporarily exchange vt for sc (with "kern.vty=sc" in
/boot/loader.conf), you should see the desired behaviour,
even though X won't work anymore (if this is important to you).
But vt seems to support what you need. See "man 4 vt" for the
following configuration entries:
In loader.conf(5) or sysctl.conf(5):
Maybe this can help?
