you can use NOPASSWD option in sudoers file to indicate specific
users/commands that don't require any authentication.

for example, I have done this in the past (no longer necessary)

# Cmnd alias specification
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
