Something must be wrong....   I also thought that a hyperthreading CPU would 
only steal cycles from each other and would in total amount to one cpu at 
best.  But on a challenge from someone on the SuSE list, I ran some test with 
setiathome and found that damn, I could do about 95% x 2 work using 
hyperthreading.  It does work.  Don't know why it doesn't show on your 
laptop.
