If your output if n-best, you can apply the disambig or hidden-ngram 
taggers to each of the hypotheses, and
then extract the 1-best segmentation by some criterion. 

If your output is in lattice format, things are more involved. You'd 
have to edit the lattices to insert nodes
representing the different tagging choices (e.g., 
boundary/no-boundary).  then rescore the lattice with
the tagging LM to extract the best hypothesis.
