My Dell Pentium-M speedstep works fine as far as I know, but I'm not 
using dapper yet.  I hope that doesn't change.  I would have to change 
distros if there wasn't a way for me to have speedstep in Dapper. 

Does /proc/cpuinfo list anything for speedstep? Mine lists Stepping: 8

Also, to check to see if how my processor was stepping I added the gnome 
widget to my taskbar that showed me the cpu speed.  Very nice, I can 
actually see my cpu clock down to 800 and then jump up to 1600 when I 
give it a good task.  This might not help at all, but I thought I would 
mention it all the same.  I enjoy seeing my processor step up and down.
