CPU
CPU Frequency Scalling (Intel SpeedStep) works perfectly for kernel settings as shown below.

I have built-in kernel CPU features so I don't need to load proper modules. You can additonally install -- it is useful for ACPI configuration, and of course to check your installation. See also Gentoo power managment guide. cpufrequtils

If everything is ok you should see output like this:

cpufrequtils

To control CPU frequency You can use i.e. or.

Xorg 7.0
Install xserver: Installing Xorg7.0

Edit :

To check if you have DRI enabled: DRI

Glxgears gives me ~950FPS.

Native resolution
With newer Xorg (>= xorg-server-1.3.0.0 and xf86-video-i810-2.1.0) native resolution works out-of-the-box. In case of older configurations: Installing 915resolution

Change settings to in :
