Hello,

I have a new laptop (Core duo 2) and I plan to run Xen on it (using
Windows in a DomU). The laptop won't be connected to a power plug all the
time. So it would be nice to have the possibility to set the CPU frequency
to a lower value to save some power. I only found the patch by Matt Yourst
for AMD k8 processors
(http://lists.xensource.com/archives/html/xen-devel/2006-04/msg00484.html).

Is a patch for Intel Core Duo 2 processors out there?

Matthias Pfafferodt
