Indeed this patch is already upstream and will land in 2.6.32.
Unfortunately the current kernel for Karmic is frozen except for
critical bug fixes.  As a workaround for now, I'd encourage you to use
an upstream kernel for now:


I've pasted the upstream commit id below:

    Input: atkbd - allow setting force-release bitmap via sysfs
    There are more and more laptop requiring use of force_release quirk
    for their multimedia and other specialized keys. Adding their DMI data
    to the kernel is not sustainable; instead we will rely on help from
    userspace (HAL) to do that for us.
    This patch creates a new 'force_release' sysfs attribute (that belongs
    to serio device to which keyboard is attached) which can be used to set
    up force_release keymap. For example, Dell laptop owners might do:
    echo 133-139,143,147 > /sys/devices/platform/i8042/serio0/force_release
