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.

Hi, mjg-

Can you add this to your tree for 2.6.39 (or 2.6.40 if you think it's
too late for a missing device ID)?  This is needed on a bunch of new
ThinkPad laptops (including mine).  Henrique asked me to forward my patch
or this one, and I think this one is slightly prettier.
