    Ah right, yes, so probabyl sony-laptopt has nothing to do with it.

    THen the problem is simply that the acpi events are not coming through
    when pressing the respective keys.

    But *that* might be part of the sony-laptop kernel module?

    TREWOFFE (n.)
    A very thick and heavy drift of snow balanced precariously on the
    edge of a door porch waiting for what it judges to be the correct
    moment to fall. From the ancient Greek legend 'The Treewofe of
    Damocles'.
