I am not sure how different they are though. I tried K10, but it did not work out of the box. I am looking into k10temp.c driver now.

Kapil: I was trying to avoid updating the kernel because my current kernel is setup for running different type of benchmarks etc. Seems like I can't avoid updating the kernel; I will do it.. Just for my understanding: Currently, when I run "sensors" command, I am getting three values (apparently wrong), temp1-3. So, what do you think is happening that is causing these values wrong? And, how is it going to be fixed by updating the kernel? Although we don't know yet, but, I am hoping that by updating the kernel and loading the k10temp kernel, I would be able to see readings from thermal-diode (core-temperature) along with the current readings from thermal-resistors.
