I believe that this patch is a response to
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/133636

But as I stated in that bug description, the fix did not work for me.
Also both R61, T60, T61 and T61p owners responded that their
dmi-manufacturer was listed as LENOVO. So I'm quite dubious if these
entries will match any machines at all?
