info about needed modules in kernel-config

This document seems rather old, but I've been able to install OpenVZ without any prior knowledge of the subject on a debian stable (squeeze) fresh install, using only the default repositories and apt-get commands and the instructions for debian lenny. My point is that the article can be quite confusing and a simpler one could be written. And in case anybody needed to install openvz in an old debian version, you could keep a link to the current article. --[[Special:Contributions/95.21.175.189|95.21.175.189]] 16:20, 1 August 2011 (UTC)
