Couldn't find anything related during > a quick glance at the zfs manpage (on a 7.2-release/amd64 system with > zfsv6). Take a look at /etc/rc.d/zfs. Since /etc/fstab is not a supported way for adding swap on zvols, /etc/rc.d/zfs script (executed during boot if you have zfs_enable="YES" in your /etc/rc.conf[.local]) will execute "swapon" on all zvols that have org.freebsd:swap=on.
