I second Raphael's experience.  Mine is a VGN-Z570AN, Ubuntu Jaunty,
and whether I use one or two fingers, synclient reports 40 - with
occasional seemingly random variations.

Actually, I am not especially keen on two-finger scroll, I can manage
by setting aside a side strip for scrolling.  However, I really
miss an easy middle button; on another notebook's synaptic touchpad I
configured two finger tap to behave as middle button.  Looks like this
is impossible with an Alps.

It was a real turn off when I found out that such an expensive
notebook had a second rate touchpad.
