This makes me wonder.  Are you enabling dual core from the mother 
board?  This is not a common option.  What is common is enabling and 
disabling HT on the mother board.  With HT enabled and 2 dual core CPUs 
you should see 8 CPUs in Linux.  (I don't know if the 5160 is HT capable).

Some motherboards don't like Hyper Threading with multiple CPUs.

So my question is:  Is Hyper Threading turned off on the mother board?
