Hello all,

A simple command is:
  watch -n 5 grep MHz /proc/cpuinfo
or with powersaved running (in Alexey's case, it is running)
  watch -n 5 powersave -r

KPowersave also shows real-time CPU speed, which it gets from
powersaved. (Does powersaved use information from /proc?) The sysinfo
KIO slave (which is 'My Computer') uses /proc directly.
