Driver `lm78':
* ISA bus, address 0x290
Chip `National Semiconductor LM78' (confidence: 6)
Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no):
Starting lm_sensors: loading module lm78 No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

Unloading i2c-dev... OK
うーむ。載ってないのか。

と追記して
service snmpd restart
で・・・
