suid/guid question

[plasmid]

I was doing some reading over at linuxdoc.org on security, and they said to beware of files that were suid/guid. I used a find command with some parameters that were supposed to list every file that was suid/guid. The list I recieved concerned me because some of those files are games (e.g /usr/bin/gnome-xbill) should I be concerned of any of theses???
Here is the list I got:
/usr/X11R6/bin/xload
/usr/X11R6/bin/imwheel
