I am DEFINITELY not an expert on sudoers file but...

# tail -n 5 /etc/sudoers
Cmnd_Alias IPOD=/sbin/modprobe -r sbp2
Cmnd_Alias EJECT=/usr/bin/eject /dev/sda2,/usr/bin/eject /dev/sdb2
# User privilege specification
craig   ALL=(ALL) ALL
craig   ALL= NOPASSWD : IPOD, EJECT

makes me believe that I could only use modprobe and eject as prescribed
if I didn't have the ALL=(ALL) ALL designation.
