I think I would go ahead and list the superclass parameters and put the 
new one at the end:
     def __init__(self, opt_1, opt_2, opt_3, opt_n, just_a_sub_option):

>         MySuperClass.__init__()                    # Should this be first?  What args to use? **args?

        MySuperClass.__init__(self, opt_1, opt_2, opt_3, opt_n)

John's method will also work but I prefer to add the new parameter at 
the end of the argument list.
