Subject: [093/101] thinkpad-acpi: module autoloading for newer Lenovo ThinkPads.

2.6.33-longterm review patch.  If anyone has any objections, please let us know.

------------------

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

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.
