Well, it needs to open the raw block device and read data direct from
it.  That doesn't need root access -- being a member of group 'disk'
gives you sufficient access to do it as a normal user. 

The permissions on the device node are what matter:

daniel at enki:~$ ls -l /dev/sda1
brw-rw---- 1 root root 8, 1 2007-03-27 16:07 /dev/sda1
