What are your synaptics settings?  If scale_z is not 32 then you need to
update again.  I bumped up the default scaling for this variable, if it
is still a bit jumpy then you can increase scale_z some more.  You need
the very latest synaptics driver to do this though.

I think Martin said he was going to look at this - again, I only have a
clickpad on my laptop so it is hard to test.

It could be a software feature - if it is then we can do the same sort
of thing I did for emulating 3 buttons on a clickpad (by default that
only reports a left click which is why I started hacking on the driver
in the first place...)
