Interesting.  I read somewhere that the boot partition should not be too 
large as the entire partition is loaded into memory.  I re-partitioned 
my drive to create a 64KiB freebsd-boot partition and I no longer get 
the error.  It would appear that there is an undocumented maximum size 
to the freebsd-boot partition.  In my case, a 1MiB boot partition was 
too large.

Now I need to teach gptboot in ad4p1 how to find my root partition in 
ad4p4 without manual intervention.  Is there a GPT equivalent to boot0cfg?

gptboot currently attempts to boot:

    0:ad(0p2)/boot/kernel/kernel

I'd like it to boot:

    0:ad(4p4)/boot/loader

How does the boot process discover the partition in which the gptboot 
loader resides?

And GPT is pretty damn slick.  Nice work FreeBSD hackers.


Thanks,
