Well, I have the script changing cpu freq:

#!/bin/sh
l=0

echo "set userspase scaling governor"
echo userspace > scaling_governor

while [ true ]; do
    freqs="104000 208000 312000 416000 520000 624000"
    r=0
    echo "--------- LAP: $l -----------"
    for f in $freqs; do
        echo "`date` -- round: $r, curfreq:
`cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed`, newfreq: $f"
        echo $f > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed
        echo "changing to $f done, curfreq is
`cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed`"
        r=`expr $r "+" 1`
        sleep 30
    done
    l=`expr $l "+" 1`
done

Runtime is 30 minutes at the moment - still alive. Suspend/resume not tested
this way. But, it may not wake even without voltage changer, so...
