Sorry, I can't get that website to come up.

Anyway, as you probably know, hyper threading is not the same as having 
a second core.  To the best of my knowledge, a dual-core CPU will always 
show 2 cores regardless of whether it supports hyper threading.  I don't 
think you will see each core twice if they are hyper threaded.
