For anyone trying to get this to work with more recent Ubuntu versions, I can confirm that setting the kernel option works for me on my Thinkpad T43 on Ubuntu 9.04.

Setting the max_cstate=3 was sufficient, and I am noticing little difference in power consumption (when idle with the lowest screen brightness I am at about 15W), so from my perspective this problem is solved.

Applying the setting to /etc/modprobe.d/options did not work for me.
