I thought I would have to get a patched kernel image built for you to test this, but v4 of the patch is now commited and has found its way to the latest daily ubuntu mainline build already [1] (see [2] for more information about the mainline builds). It will also be included when 2.6.35-rc4 is released. So when you get your test partition up and running, you can test the latest daily mainline ubild or the mainline build of 2.6.35-rc4 where hopefully this problem is fixed (it is reported on the mailing list that it does not solve the problem for at least one eDP laptop).
