Comment(by lt_henry):

 I also own a Eee 701, but I am afraid Celeron M cpu does not provide
 speedstep technology. Anyone is sure about this?

 However, on current Core Duo/Atom processors CPUFrequency don't show any
 frequency. I find this is a bug (maybe an implemented feature) on
 enhanced_speedstep driver. I've done a small patch that enables driver
 working on my Centrino Duo @ 1.6Ghz laptop, It detectects just highest and
 lowest speeds, and it randomly crashes (no kdl) working on Dynamic mode. I
 find it stable working in Low energy profile. I am going to try to upload
 this patch today.
