Yes they should be somewhere in the core imho.

Yes it has two analog pins.

I think thats because of the load balancing.

Many thanks for the test. Now we know:

1) it works on single core
2) it works on dualcore
3) it works on 2x CPU
4) it shoud work on 2x dualcore ;)

Just a curios did you test with latest version :) ? (it has dword reads for temps)
