It's that time of the year again... Here is a linux 3.2.1 config file for ALIX 2. It's a basic config. It includes upport for the integrated Ethernet, USB, GPIO and watchdog. Also included is WiFi stack + an Atheros card, but you probably want to change this to suit your needs. Compared to the 3.0 version, this has working LEDs thanks to the new platform driver by Ed Wildgoose. The button should be accessible via raw gpio, but not via the evdev interface. Hopefully the platform driver will be extended to cover this, but this requires an GPIO evdev driver first.
