I'm not sure why the sudo (with restricted commands) is not an option.
 Before the existence of sudo,
I would have written a trivial C program which just exec()ed the real
program and installed it with the setuid bit set.   Here is some
UNTESTED code:

main(int argc, char **argv)
{	
	setuid(0); /* make real uid root as well */

	execvp("real program", argv); /* pass arguments through unchanged */
}
