Probably either Knoppix or the Debian CD will work.  With Knoppix, just boot 
from the CD, mount the partition on which is /etc, and edit the file.

Commands used will be approximately (you will need to use the correct block 
# fdisk -l
# mkdir /mnt/tmp
# mount /dev/sda1 /mnt/tmp
# nano /mnt/tmp/etc/passwd
# umount /mnt/tmp
# reboot
