On laptops it is almost never possible to access monitoring chips
directly, one has to go through ACPI or a vendor-specific layer. So
Kenny should prepare himself to the idea that the emc1403 driver in
linux-next will most likely not work. But it's certainly worth a try
anyway.

Kenny, how do you know that your laptop has an EMC1402 chip? Doesn't
the ACPI thermal driver work for you? Did you try the vendor-specific
driver for your laptop? Some of them (asus-wmi, compal-laptop,
eeepc-laptop and thinkpad_acpi) provide temperature readings.
