I have this problem on a T60p as well, and the modset=0 hack resolved it. After significant research, I believe this problem is resolved upstream. See fdo bug 25741 http://bugs.freedesktop.org/show_bug.cgi?id=25741. A patch was committed on 2010-03-09. I haven't found where it has been integrated as yet.
