It is, indeed, but you don't need any of these drivers anyway. > Also, smbus seems to be going nuts in my dmesg: > > Code: > i2c_adapter i2c-0: smbus word data - addr 0x4f, read 0x0000 at 0x02. I suspect that one of the i2c busses on your system is broken, causing sensors-detect to misdetect lots of chips.

Your problem lies well before the configuration step. > My computer is a Dell Dimension 8250. What makes you think this model has a thermal sensor chip lm_sensors can use?
