[Bug 422858] Re: Atom N280 frequency scaling not supported

[Matko Jun]

As far as i know (and wikipedia confirms:
http://en.wikipedia.org/wiki/SpeedStep#Operating_system_support) XP does
use EIST. When idle my computer -> properties shows 800MHz, under load
(youtube with HD video) it rises to 1,66GHz. EIST in XP is disabled when
power managment profile is set to "Home/Office Desk".

Quote from wikipedia:
"Under Microsoft Windows XP, SpeedStep support is built into the power management console under the control panel. In Windows XP a user can regulate the processor's speed indirectly by changing power schemes. The "Home/Office Desk" disables SpeedStep, the "Portable/Laptop" power scheme enables SpeedStep, and the "Max Battery" uses SpeedStep to slow the processor to minimal power levels as the battery weakens."

Maybe there is a problem in Ubuntu acpi module (or some other
module(s)?), maybe trying to upgrade some modules to lucid ones will fix
this annoying problem?
