That's not true. I have a 2.6 GHz Northwood, and it supports 
HyperThreading (however I'm not running FreeBSD on it, so I can't help 
you with SMP).
You can use the Intel Processor Spec Finder 
( to discover the capabilities of your 
CPU, but I think the "HTT" that appears in the dmesg output stands for 
Hyper Threading Technology.
