Aren't they SMT-enabled processors? The new P4 Xeons can run more than
one thread at a time, and look rather like two CPUs to the OS. I
remember hearing about licensing problems with some SMP software as a
result of this... win2k server comes to mind.
I'm pretty sure the number of "real" versus virtual CPU's can be
detected but perhaps kernel support isn't there yet...
So, there probably aren't any cleverly hidden chips in your box :)
