Or alternatively, write a C program to wrap the script, and make
the compiled binary suid.

     void execl (char *path, ...);
     extern int errno;

     int main (void) {
       setgid(0);
       setuid(0);
       execl("/usr/sbin/myscript", "myscript", (char *) 0);
       return (errno);
     }

ought to work for most purposes.
