CentOS - Jan 2013 - sysctl -p at startup?

I understand that the contents of /etc/sysctl.conf should be read and executed
at system startup.  However that never happens and I have to run sysctl -p after
every reboot to get the settings I want.

This is happening on every CentOS machine and VM I have.   I can see in the
startup scripts that "sysctl -e -p /etc/sysctl.conf >/dev/null
2>&1"
  is run at start up by the "apply_sysctl" function, yet the settings
are never correct unless I run sysctl -p on the command line.

Anybody know why that would be?

I am running the latest updates on CentOS 6.3

I have to run sysctl -p manually in order to stop kernel messages being
printed to the console as even though i have them configured off in my
sysctl this is overridden at some other point and i get to find out all
about SoftMAC and its scanning ways
