Is it correct that the Dell E521 does not have any sensor chips? I can't find any of the supported devices listed in iic(4) in dmesg. Or does the system have some other unsupported sensor device? dmesg from 4.0 release (non-MP) below (as mentioned earlier when I asked about this machine: ohci has been disabled, bce is not in GENERIC).
