Perhaps it's time to start asking a question that's been bugging me for a
while now. A loong time ago I implemented an early fix from this thread
(patching alps.c and remaking psmouse.ko) that has sort of jury-rigged me
along until now--it works, mostly, I've got vertical scrolling though the
thing is still damn sensitive even with disable-touchpad-while-typing. But
every time I update my ubuntu, it complains that my psmouse.ko is "third
party" and at the least doesn't replace it. My question: At what point will
there be something in the standard update that will be at least as good as
what I've got, and mostly, what will I have to do at that point to have the
update replace my mods?
