Having done that, CARP is now acting as it should, though now I have a new challenge with devd and automatic firing of scripts during CARP failover. It appears that the documented method of doing this at http://www.freebsd.org/doc/handbook/disks-hast.html no longer works with the suggested devd.conf setup;

You will need to change this to something like (as taken from man carp):
         match "system"          "CARP";
         match "subsystem"       "[0-9]+@";
         match "type"            "(MASTER|BACKUP)";

The subsystem now is generated as
snprintf(subsys, IFNAMSIZ+5, "%u@%s", sc->sc_vhid, sc->sc_carpdev->if_xname);
