Here is a short update on my older post on configuring linux kernel for use on ALIX2.
The general points are still valid. The specific locations of the options might have changed. But to provide something more up to date, here is a working linux 220.127.116.11 configuration for ALIX 2.
Use this only as a starting point to get a configuration that works well for you. There are plenty of options that are specific to my setup and you certainly want those changed. But you should be able to boot with this one.
