lmsensors & hddtemp stopped working under FC3

[Andrew Konosky]

I did a fresh install of FC3 last night, and after finally figuring out 
how to get yum working again, I tried to set up my gkrellm monitors. I 
installed the hddtemp monitor, but when I run the hddtemp /dev/hda 
command, it says the drive is not in the db (which it is, I checked...), 
but it still reports a temp of 27 C and hdb reports 26 C. gkrellm 
detects the sensors, but keeps reporting 0 C for both drives

These lines are in my /usr/share/hddtemp/hddtemp.bd. hda is a retail and 
hdb is an OEM drive, so they have different serial #'s.

I ran sensors detect as root and let it create the config files. I added 
the modprobe lines for i2c-isa and i2c-viapro in /etc/rc.local just like 
I did in FC2, but when I run /usr/bin/sensors -s or type the sensors 
command, it says no sensors found...

How do I get this working under FC3?
