I forgot to answer this one.

In FreeBSD you can use nvram (see man nvram) to set variables in OF.

To enable/disable auto-boot? you just do this:

% nvram auto-boot\?=true
% nvram auto-boot\?=false

Important, do not forget the backslash to before the ?.

% nvram -p shows the content of the nvram.

You can also set the boot-device, here it is important to quote the two 
backslashes before :tbxi. E.g:

% nvram boot-device=sd0:2,'\\':tbxi


If something goes wrong, you can always do a 'reset-nvram' and 
'reset-all' inside OF.
