Problems

    The fn-brightness (Fn + Home/End) hotkey won't work. I don't change the brightness from time to time, so currently I just added this line into rc.local:
      echo 6 > /sys/class/backlight/acpi_video1/brightness
      
    The Wlan led won't work. The wireless card works.

    Since using kernel 2.6.26, the two issues above have been solved. Wlan led is supported since kernel 2.6.26. I have no idea about since when the brightness keys are supported.

    The volume keys won't work.
    I use keys defined in fluxbox to control the volume. See Fluxbox volume keys configuration.
