You need setuid - the program has to belong to root or whoever you su to.
Assume your file is named "myfile" someuser is whover you su to - could be root
This will work ONLY if the filesystem where you have "myfile", will allow setuid. The chmod 4711 command sets setuid, and sets permissions to 711. to do a setgid try chmod 2711 [filename]. You do this if having group permissions lets the program run correctly.
Note: setuid programs unless written REALLY well are a security risk.
