Don't you mean "gpart bootcode -b /boot/boot ad6s1"

If you say "-i 1 ad6", then what you want is bootcode
in a partition that is controlled by the scheme on ad6
(the scheme on ad6 is the MBR). You can't do that,
because that partition is sub-partitioned by the BSD
scheme.

Since you want bootcode in the BSD scheme, you need
to add bootcode to ad6s1.

Bootcode for the BSD scheme is not present in 7-STABLE yet.
I just recently added that to -CURRENT (I must have missed
it) and I need to get around MFCing it. Feel free to do the
MFC for me. The code has been in -CURRENT long enough to do
a MFC.

FYI,
