Sorry, nothing has changed. I think we'd need someone with more experience with weighting touchpad sensor values. The current algorithm just isn't working right. Either this is only a very specific problem to only a few hardware configurations OR I'm just so used to smooth apple trackpad in OS X that I'm spoiled...
