You appear to have an unknown Super-I/O chip, presumably made by SMSC.
Could be a custom chip made by SMSC for Dell. Sometimes Super-I/O have
integrated hardware monitoring features. Without additional
information (like the name of the chip), there's not much we can do
though.

Either because the user pretended i2c-dev needn't be loaded (hum hum),
or because the eeprom driver was already loaded, and the user didn't
unload it in spite of the script asking for it.

I have since improved the script to gather information from already
loaded i2c chip drivers, hopefully this should make things better.

Quite rightly so, as EEPROMs aren't sensors, as the script kindly but
firmly reminded you above ;) Try "decode-dimms.pl" for decoded EEPROM
contents.

This is usually a good indication that there is no hardware monitoring
chip in the machine. You may try ACPI (modprobe thermal; acpi -t) as
your last hope.
