Just added the dumpdev line, here is my rc.conf
# cat /etc/rc.conf 
sshd_enable="YES"
wlans_urtw0="wlan0"
ifconfig_wlan0="WPA DHCP"
zfs_enable="YES"
hostname="blackbeast.local"
linux_enable="YES"
powerd_enable='YES'
dbus_enable="YES"
hald_enable="YES"
avahi_daemon_enable="YES"
avahi_dnsconfd_enable="YES"
mdnsd_enable="YES"
kdm4_enable="YES"
local_startup="/usr/local/kde4/etc/rc.d /usr/local/etc/rc.d"
devfs_system_ruleset="system"
quasselcore_enable="YES"
font8x8="iso-8x8"
allscreens_flags="VGA_80x60"
dumpdev="/dev/ada0p2"

and here is my fstab (I disabled geli several reboots/crashes ago, thinking 
that may be what was preventing the crash dumps, as well as changed the swap 
line to point directly to the partition, rather than the gpt label)

# cat /etc/fstab 
/dev/ada0p2 none swap sw 0 0
#/dev/gpt/swap0.eli none swap sw 0 0
proc /proc procfs rw 0 0
linproc /compat/linux/proc linprocfs rw,late 0 0
