You have been missing the boot blocks. :-)

With the "old" method, it's a simple call of fdisk and boot0cfg.
With the "new" method, you need to have a boot partition, for
example ada0p1, which is set active and contains the boot code,
in your case, the boot manager.

Have a look at Warren Block's installation guide and adjust the
bootcode command for the boot manager. See the "EXAMPLES" section
in the "man gpart" manpage.
