It appears that in FC7 /usr/bin/hddtemp is linked to "consolehelper", which is
part of the "usermode" rpm package, which uses pam to authenticate and 
run things as root:

Description :
The usermode package contains the userhelper program, which can be
used to allow configured programs to be run with superuser privileges
by ordinary users.

Anyway, thats why hddtemp (and probably the sensors plugin) works just 
fine as a regular user in Fedora.
