I do not have an answer to your request, yet I wonder:
Why do you want to run TP4 over X.25??

The main raison d'etre of TP4 over the other ones are that it handles
error correction and multiplexing (in the transport layer). But X.25 
already does this for you in the net layer, so transport doesn't have to.
You usually run TP1 over X.25, or if you have a bad X.25 net or require
extremely low error rates, TP3.

(Unless, of course, you are using X.25 as a link level connection, and
have other unreliable and/or non-multiplexing links in the end-to-end
connection.)
