And things work?  That is strange, usually the absence of "lo" will cause things like X, syslog, etc..., to sputter.

Anyway, take a look at /etc/sysconfig/network; do you have NETWORKING=yes

Loopback is started if /etc/rc.d/init.d/network is started.  Check your default runlevel and make sure that it contains a symlink to ../init.d/network.  If your default run level is 5 you want to look in /etc/rc.d/rc5.d, if 3 (non GUI) check /etc/rc.d/rc3.d.  These contain symlinks to the start/stop files of the services you want to run/not-run at that level.
