You can try to do it with gpart, maybe it will like slices of your disks better :)

E.g.: gpart bootcode -b /boot/boot ad10s1

Be warned that gpart says back something like "partition has boot code" and it's
not terribly clear what is actually meant here: "it (already) has boot code, so I
am not doing anything" or "I did my job and it (now) has boot code". It is the
latter :-)

P.S. I have a disk that was labeled from the very start with gpart - both gpart
and disklabel treat it nice; another disk was lebeled with disklabel in pre-gpart
environment and then moved to a gpart environment - gpart works good with this
disk, but disklabel barks the same kind of messages.
I guess that this happens because gpart hasn't reset to zero offset field of the
special partition c when it adopted disklabel-authored label.
