xserver-xorg-input-synaptics multiple finger

I buyed today a toshiba l300-19j laptop, with synaptics touchpad.
I wanted to use multiple finger feature like on macosx.
It looks like everything is ok:
1. the kernel recognizes:
[ 231.424535] input: SynPS/2 Synaptics TouchPad as
2. X.org recognizes:
(II) XINPUT: Adding extended input device "SynPS/2 Synaptics TouchPad"
3. synclient claims two finger support:
synclient -l |grep VertTwoFingerScroll
VertTwoFingerScroll = 1
However, when I run synclient -m 100, the "f" column has only 0 or 1, no matter
with how many finger I touch the touchpad.
I have googled the whole day, I browsed the source, even read some
marketing stuff from synaptics website,
still no success.
I have found a hardware compatibility list:
I seems outdated, I do not see any Toshiba L300 model on the list.
I couldnt find any newer compatibility list, is such exists?
So my question is, how can I make sure, if it is a HARDWARE
LIMITATION, or some software lack/bug/anything?
Is there a reliable method to check if my hardware supports multiple
finger touch or not?
I read everywhere that newer synaptics touchpads should not have any problems.
Any idea is much appreciated!
My system details:
Ubuntu 9.04 alpha 4 live dvd, with hand installed:
kernel (uname -a):
Linux ubuntu 2.6.28-6-generic #17-Ubuntu SMP Fri Jan 30 15:34:36 UTC
2009 i686 GNU/Linux
xorg.conf (I only pasted the following paragraph into xorg.conf):
Identifier "SynPS/2 Synaptics TouchPad"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "SHMConfig" "true"
Option "MaxTapTime" "0"
Option "VertTwoFingerScroll" "1"
Option "HorizTwoFingerScroll" "1"
Full xorg.conf can be found here:

If there is any more additional information you need, just reply, I
will post them.
Im mainly interested to figure out if it is a hardware limitation (I
have two days left for this;)
Thank you in advance,
