ALIX 3C3

Award BIOS do not redirect console over serial port, event all is set in BIOS - serial port is enabled and console redirection too. If you wish use all board feauter in linux, here is configuration:

CPU Geode GX/LX (nother type do not allow some next feautres)
Power management ACPI, but only a few functions are supported
CPUFREQ nothing :-(
BUS / Geode Multi-Function General Purpose Timer...
Device / SATA/PATA / CS5536 PATA support
Device / Network / 10-100Mbit / VIA Rhine support
Device / Character / AMD Geode HW Random Number Generator
Device / Character / AMD CS5535/CS5536 GPIO
Device / I2C / HW Bus support / Geode ACCESS.bus
Device / HW Monitor / lm90 (really lm86)
Device / Watchdog / AMD Geode CS5535/CS5536 Watchdog
Device / Sound / ALSA / PCI / CS5535/CS5536 Audio
Device / USB / EHCI & OHCI
Crypto API / HW crypto device / Support for the Geode LX AES engine

Kernel configuration 2.6.26 and prepared bzImage. Work fine for me.
Additive kernel options: "acpi=force mfgptfix"
LED on GPIO. How to use?
  mknod led1 c 254 6 # here is probably error in documentation
  mknod led2 c 254 25
  mknod led3 c 254 27
  # now enable output
  echo "O" > led1/2/3
  # switch off
  echo 1 > led?
  # switch on 
  echo 0 > led?
WRAP 2C

Kernel configuration:
