I use the synaptics driver on my dell d600, but the trackpad is actually 
an ALPS. The source distribution includes a file specific to ALPS pads 
(called README.alps or something to that effect if I remember correctly).

Here's my toucpad section:

Section "InputDevice"
   Driver       "synaptics"
   Identifier   "Mouse[1]"
   Option       "AccelFactor" "0.025"
   Option       "BottomEdge" "650"
   Option       "ButtonNumber" "7"
   Option       "Buttons" "5"
   Option       "Device" "/dev/psaux"
   Option       "FingerHigh" "15"
   Option       "FingerLow" "14"
   Option       "LeftEdge" "120"
   Option       "MaxSpeed" "0.9"
   Option       "MaxTapMove" "110"
   Option       "MaxTapTime" "180"
   Option       "MinSpeed" "0.40"
   Option       "Name" "AlpsPS/2 ALPS TouchPad"
   Option       "Protocol" "auto-dev"
   Option       "RightEdge" "830"
   Option       "SHMConfig" "on"
   Option       "TopEdge" "120"
   Option       "VertScrollDelta" "20"
   Option       "HorizScrollDelta" "20"
   Option       "UpDownScrolling"   "1"
EndSection

Notice for instance that the AccelFactor is around an order of magnitude 
different.
