Fedora Users — lm_sensors doesn't stay enabled!

I have gotten the lm_sensors configured to read cpu temp and other system sensors and it reports it through gkrellm. I put the initialization commands in /etc/modprobe.conf and /etc/rc.local, and it loads when I restart the system. After a few restarts or when I shut the system down for a while, the sensors won't start back up. Hddtemp starts up and works every time but lm_sensors does not.... Why?
