    nanobsd: Restore boot0cfg functionality
    
    The need for this step is fading, now is mostly used to allow the
    selection of just the two code partitions in the boot0 boot manager,
    instead of the default of allowing all four MBR slices (the other two
    being cfg and data, which cannot boot).
