For now, it seems X is required. The "switch-to-VTY-and-back-again"
solution works for me:

http://www.freebsd.org/doc/en/articles/laptop/power-management.html

In my /etc/rc.suspend:

...
/usr/sbin/vidcontrol -s 1 < /dev/console
...

In my /etc/rc.resume:

...
/usr/sbin/vidcontrol -s 9 < /dev/console
...

I've also seen various posts in forums and on mailing lists
about using the "vbetool" program (in ports), but I haven't messed
with it myself.

See here for more detail on this issue (under "Low Priority Tasks"):
