1-2 degrees is within the sensor's deviation.   Either you dont have it
working correctly or it doesn't work at all in your case.   

You also need acpi idle calls, not just apm.   now this is just my guess
but apm idle calls might either mess things up or be disabled if acpi
idle calls are used and disconnecting the cpu... either way  you can't
have this patch work and apm work at the same time.
