For this use case (desire to be able to get crash dumps while having
swap encrypted), I find that adding the "late" attribute to the
"swap" entry in /etc/fstab is useful, thus:

g1-51(12.4-S)[1] grep swap /etc/fstab
/dev/ada0s4b.eli        none            swap    sw,late         0       0

(Thta is, of course, assuming that one uses fstab to control the
swap allocation.  If not, arranging to perform the allocation as
part of execution of /etc/rc.d/swaplate -- which is what the "late"
attribute accomplishes -- should work for you.)

I have used the above technique successfully for stable/12, stable/13,
and head (current/14).
