I am not sure what is in squeeze just now, but maybe you need to tell
hal about the pad with an fdi file.

This is one I used to use on an Acer Aspire netbook:

          If on, circular scrolling is used

          For other possible options, check CONFIGURATION DETAILS in synaptics man page

On the other hand, you might need to have a udev rule something along
these lines:
-------------------------------------------------------
ACTION!="add|change", GOTO="xorg_synaptics_end"
KERNEL!="event*", GOTO="xorg_synaptics_end"

ENV{ID_INPUT_TOUCHPAD}!="1", GOTO="xorg_synaptics_end"

#name below might change with kernel? Seems to be ok to omit, but still...
ENV{x11_driver}="synaptics", ATTRS{name}=="SynPS/2 Synaptics TouchPad"

ENV{x11_options.LeftEdge}="1700"
ENV{x11_options.RightEdge}="5700"
ENV{x11_options.TopEdge}="1700"
ENV{x11_options.BottomEdge}="5100"
ENV{x11_options.FingerLow}="25"
ENV{x11_options.FingerHigh}="30"
ENV{x11_options.MaxTapTime}="180"
ENV{x11_options.MaxTapMove}="220"
ENV{x11_options.VertScrollDelta}="100"
ENV{x11_options.MinSpeed}="0.09"
ENV{x11_options.MaxSpeed}="0.6"
ENV{x11_options.HorizEdgeScroll}="true"
ENV{x11_options.TapButton1}="1"
ENV{x11_options.SHMConfig}="true"

LABEL="xorg_synaptics_end"

-----------------------------------------------------------------------
Both of those were used by older versions of xorg for a while.
Either one or the other, not both together. I can't remember the 
details now. Both appear in the debian bug tracker, so I am surprised
that you didn't find them.
