Subject: [v2.6.34-stable 098/165] thinkpad-acpi: module autoloading for newer Lenovo ThinkPads.

From: Manoj Iyer <manoj.iyer@...onical.com>

                   -------------------
    This is a commit scheduled for the next v2.6.34 longterm release.
    http://git.kernel.org/?p=linux/kernel/git/paulg/longterm-queue-2.6.34.git
    If you see a problem with using this for longterm, please comment.
                   -------------------

commit 9fbdaeb4f4dd14a0caa9fc35c496d5440c251a3a upstream.

The newer Lenovo ThinkPads have HKEY HID of LEN0068 instead
of IBM0068. Added new HID so that thinkpad_acpi module will
auto load on these newer Lenovo ThinkPads.
