I'm posting this to the list, because I couldn't find it documented 
anywhere. I was looking around about how to install the fbsd boot 
manager to the boot sector of this partition, but it seems it is done by 

Removing 'kernel /boot/loader' and adding 'chainloader +1' (instead of 
keeping both, like some docs suggest) worked perfectly.

Thanks Joe!
