on my Vaio z11-mn, it does.
I didn't directly succeed with making double-finger scroll happen since the w value was always to 0 whereas sinclient -l had a doublefinger minw to 7 ... which I had to correct to 0 to make double-finger scroll working.

The french thread about it was at :

Hello Anthony,

On my (ubuntu Karmic@) z21-mn_b with AlpsPS/2 ALPS GlidePoint-device it
doesn't give the information about pressure as presupposed in that
mini-how-to you linked to - touching with two fingers the pressure value
does not increase - so playing with values around 80, 85 or whatever you
want will not bring the result needed for emulating two finger mode in
that way..
I guess you will have to take an other device with a different chip-set
or glide-sensor..

Works much more smoothly on the Nvidia Card too...

Does anyone know if Multi-Finger gestures are supportable on the Vaio
Z touchpad?

        Hello everyone,

        Before using my Vaio on Linux, I was using a Mac running OS X.
        A feature that I really missed was the two-finger horiz/vert
        scroll that Macs come enabled with in OS X.  I have figured
        out a rather hackish way to get this far to enable it on my
        Vaio Z520N.

        1)  copy the shmconfig.fdi to /etc/hal/fdi/policy/
        2)  cd into /usr/share/hal/fdi/policy/20thirdparty/
        3) backup existing 11-x11-synaptics.fdi
        4) copy in the updated one I've provided

        In order to tweak the settings, from a terminal you should
        $ synclient -m 10
        and pay attention to the z axis when using two fingers, the
        value it outputs can be edited in the 11-x11-synaptics.fdi
        file to your liking

<merge key="input.x11_options.EmulateTwoFingerMinZ" type="string">100</merge>
        ...My value is at 80 or 85 (still playing with it)

        adjustments to my trackpad

        I believe there are still a couple of issues however...
        My main question is, now my touchpad doesn't seem to work from
        login screen, not a huge deal, but could anyone give me some
        advice?  Im running Ubuntu Jaunty with 2.6.28-15 generic.
        Also, I will have to add more parameters to get a more
        functional trackpad with the precision the Mac has.

        Many people just carry a bluetooth or mini-usb mouse.  I for
        one really do like to utilize my trackpad, and these
        instructions have helped quite a bit...

        Hope someone else finds them helpful
