Any chance it could have something to do with the Xeon's 
"Hyperthreading" technology?  I think I read something somewhere 
(helpful, I know) that mentioned that the Linux kernel can treat the P4s 
with hyperthreading as virtual dual processors.

I haven't gotten a chance to play with these processors yet, so I can't 
tell you for sure.
