Yes you do, and for /bin/mount, it already should be 4755 root:root.SUID bit makes the program to be executed in the rights the owner of it, so if you want to have a program run SUID root you will have to chown root it. The same goes for SGID.
'man chmod' would have happily told you just that.
P.S. Beware that SUID/SGID root is a potential security risk. -- [email protected] mailing list
