sudo problems

[ultrakorne]

hi, i have a problem with my warty, i cannot tell sudo to execute a 
command without a password, i did as man sudoers tells
i need to run the script savepower without pass

here is my config

# sudoers file.
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the man page for details on how to write a sudoers file.
#

# Host alias specification

# User alias specification

# Cmnd alias specification

# Defaults

Defaults !lecture,tty_tickets

# line added by me
ultra ALL= NOPASSWD: /usr/bin/savepower

# User privilege specification
root  ALL=(ALL) ALL

# Added by Ubuntu installer
ultra ALL=(ALL) ALL


if i execute savepower with user ultra, the system ask me for the 
password..
