To use rename_segments in combination with automodel, use the 
special_patches() method, as detailed at
http://salilab.org/archives/modeller_usage/2009/msg00245.html

A minimal script which should do what you want is:

from modeller import *
from modeller.automodel import *

class MyModel(automodel):
    def special_patches(self, aln):
        self.rename_segments(segment_ids='A', renumber_residues=5)

log.verbose()
env = environ()

a = MyModel(env, alnfile='alignment.ali',
            knowns='5fd1', sequence='1fdx')
a.make()
