That's great if you're happy with those settings.  The problem is that 
unless the device is recognised by the right driver, there's no way to 
enable/disable or tweak the settings.  In my case, I would like to 
increase the threshold for tap-to-click: I have found myself 
accidentally clicking on things (including adverts on web pages!).

Have you seen a tarball for the '901?  I can only find them for the 
non-Atom models.  I don't think they bother to produce them until 
someone threatens to sue.
