There are ACPI sensor drivers for some machines: asus_atk0110, eeepc-laptop and
thinkpad_acpi. However, I agree that the message "ACPI: Device needs an ACPI
driver" is misleading. The device _may_ need an ACPI driver, if the BIOS
implemented an API for the device in question (which, AFAIK, can't be checked.)
If not, then either the generic "thermal" ACPI driver may be used, or nothing
can be done (other than a white list, if we really want to get hardware
monitoring on some machines.)

I'll send a patch clarifying this log message.
