This laptop is operating under Kernel version 2.6.27-6-generic #1 SMP

Basic Installation of Ubuntu:

Downloaded Alternative Install-CD for Xubuntu 8.10 and installed. After installation deactivated atheros-drivers under system -> hardware-drivers.

Unresolved issues

Brightness-control seems not to work.
When Shutting down, the system does halt put the power is not turned off. (resolved by an automatically updated ACPI-System)

Brightness-Workaround

Use the following scripts:

brightness.sh, invoke with brightness.sh [up|down]
#!/bin/bash

if [ "$1" == "up" ]; then
        echo YourPassWord | sudo -S ~/bin/video_brightnessup.sh
fi

if [ "$1" == "down" ]; then
        echo YourPassWord | sudo -S ~/bin/video_brightnessdown.sh
fi

~/bin/videobrightness_up.sh

#!/bin/bash

CURRENT=$(grep "current:" /proc/acpi/video/VGA/LCD/brightness |awk '{print $2}')

case "$CURRENT" in

        100)
        echo -n 100 > /proc/acpi/video/VGA/LCD/brightness;
        ;;
        80)
        echo -n 100 > /proc/acpi/video/VGA/LCD/brightness;
        ;;
        70)
        echo -n 80 > /proc/acpi/video/VGA/LCD/brightness;
        ;;
        60)
        echo -n 70 > /proc/acpi/video/VGA/LCD/brightness;
        ;;
        50)
        echo -n 60 > /proc/acpi/video/VGA/LCD/brightness;
        ;;
        40)
        echo -n 50 > /proc/acpi/video/VGA/LCD/brightness;
        ;;
        30)
        echo -n 40 > /proc/acpi/video/VGA/LCD/brightness;
        ;;
        10)
        echo -n 30 > /proc/acpi/video/VGA/LCD/brightness;
        ;;
        *)
        echo -n 100 > /proc/acpi/video/VGA/LCD/brightness ;
        ;;
esac

And simmilar video_brightnessdown.sh

#!/bin/bash

CURRENT=$(grep "current:" /proc/acpi/video/VGA/LCD/brightness |awk '{print $2}')

case "$CURRENT" in

        10)
        echo -n 10 > /proc/acpi/video/VGA/LCD/brightness;
        ;;
        30)
        echo -n 10 > /proc/acpi/video/VGA/LCD/brightness;
        ;;
        40)
        echo -n 30 > /proc/acpi/video/VGA/LCD/brightness;
        ;;
        50)
        echo -n 40 > /proc/acpi/video/VGA/LCD/brightness;
        ;;
        60)
        echo -n 50 > /proc/acpi/video/VGA/LCD/brightness;
        ;;
        70)
        echo -n 60 > /proc/acpi/video/VGA/LCD/brightness;
        ;;
        80)
        echo -n 70 > /proc/acpi/video/VGA/LCD/brightness;
        ;;
        100)
        echo -n 80 > /proc/acpi/video/VGA/LCD/brightness;
        ;;
        *)
        echo -n 50 > /proc/acpi/video/VGA/LCD/brightness ;
        ;;
esac
