Comment 46 for bug 344252

The only way around it is to create a cronjob as root and reset to ondemand every once and awhile:

cronjob -e

add a job (every minute)

*/1 * * * * /usr/bin/cpufreq-set -g ondemand -d 1000000 -u 1833000 -c 0
*/1 * * * * /usr/bin/cpufreq-set -g ondemand -d 1000000 -u 1833000 -c 1

Ugly as hell but at least it keeps the heat and battery drain out of my system. Ubuntu really needs to get a grip on power saving =(

Btw. this is Ubuntu 10.10 - the Maverick Meerkat on an IBM X60
