Try setting the sysctl kern.geom.label.debug=2 (you will need to put it
in /boot/loader.conf and reboot since you built the module into the
kernel).  That should print out some debugging as to what filesystems
geom_label sees and why it is rejecting yours.  In my case, my /usr
filesystem doesn't get a label because I have grown the partition it
lives in so that the filesystem size in the superblock doesn't match
the partition size anymore.  / and /var 's labels do appear though.
