Your CPU may support hyperthreading. Older versions of the driver 
don't take this into account.

Yes.

Newer kernel version, most likely.

No idea what is going on. You might try to build and compile the latest
version of the coretemp driver to see if it improves the situation.
You can download it from http://roeck-us.net/linux/drivers/coretemp/.

Can you provide output of /proc/cpuinfo ?

Thanks,
