Comment 6 for bug 355232

I am in the same boat as most ppl above. I have been using ubuntu since breezy and undervolting the AMD Turion on my laptop since feisty. Usually I check to make sure the usual suspects (X, suspend/hibernate) have no issues before upgrading but did not think something basic as acpi/powernow would be changed!

Undervolting saves battery life, cpu temperature and my hands (from CTS).

It'll be good to have this back as a module and not in the kernel.
