Generally, this works on all iBooks2.

I would try it with Minimum and maximum speed.

case "$2" in
ac)
  # GER: Setzt bei Netzbetrieb die Maximalgeschwindigkeit
  # ENG: Set the maximum speed at AC-Power
  echo -n "0%100%100%performance" > /proc/cpufreq
  # GER: Man kann das auch so machen:
  # ENG: Another way to achieve this is:
  # cat /proc/sys/cpu/0/speed-max > /proc/sys/cpu/0/speed
  ;;
battery)
  # GER: Setzt bei Akkubetrieb die Minimalgeschwindigkeit
  # ENG: Set the minimum speed at Battery-Power
  echo -n "0%0%0%powersave" > /proc/cpufreq
  # GER: Man kann das auch so machen:
  # ENG: Another way to achieve this is:
  # cat /proc/sys/cpu/0/speed-min > /proc/sys/cpu/0/speed
  ;;
esac


A good tutorial on the cpu-speed can be found here:
