I just tried to search in Debian and Fedora packages but didn't seem to find anything related. I searched "hdlc" and "x25". The only things I can find are "AX.25" related things. But "AX.25" is not related to "X.25". I guess a script that brings a network interface up might not be very useful? So we might not be able to find it in public repositories.
