Comment 1 for bug 199682

Thank you reporting this bug.

The next version of Ubuntu (Hardy) is in development and it would be wonderful if you could test this issue with a recent LiveCD of Hardy.
You can download the cd here: http://cdimages.ubuntu.com/releases/8.04/alpha-6/

Also, for debugging hotkey issues and finding specific information about the situation this guide is helpful: https://wiki.ubuntu.com/LaptopTestingTeam/HotkeyResearch
Please follow one of the methods to determine the keycode of the non-working keys.
Also attach the file lspci-vvnn.log after running this command in the terminal: sudo lspci -vvnn > lspci-vvnn.log

Thanks for your help!
