They probably wouldn't want to do it because you can get a performance DECREASE in some applications from it. All kinds of webpages tested the crap out of the P4-3.06HT and observed a -20% performance drop up to a 20% performance increase. I'll wait for AMD's multi-cored Hammer cpu. No fake cpus for me. :)
