Peter,

I really see no big advantage to using a private address range in the DMZ.  Since the 
DMZ is usually used for Semi-protected systems that are publicly accessible, you would 
need to convert these hosts to public addresses anyway.  Save the private address 
ranges/NAT for your internal private network.
