I've gotten the mini notebook Sony Vaio P sold in Russia, concretely the model VPCP11S1R/D

Here are collected notes on GNU/Linux installation efforts there:

So the recommended installation approach is:

$ sudo add-apt-repository ppa:gma500/ppa && sudo apt-get update && sudo apt-get install poulsbo-driver-2d poulsbo-driver-3d poulsbo-config mplayer
