Guillem says you must be confused.  He was interested in adding support for
kernel of FreeBSD, not grub-set-default.

Franklin, implementing grub-set-default is relatively easy, and a good way
to learn about how GRUB works.

Basicaly, you just need to do something like add a variable similar to this
one:

  ./kern/i386/pc/startup.S:VARIABLE(grub_install_dos_part)

which is initialised in:

  ./util/i386/pc/grub-setup.c:                                   + 
GRUB_KERNEL_MACHINE_INSTALL_DOS_PART);

based on predefined offset in:

  ./include/grub/i386/pc/kernel.h:#define GRUB_KERNEL_MACHINE_INSTALL_DOS_PART  
  0x14
