Even though there is increased support for the Synaptics devices under 
2.6 kernels, you still need to compile a separate Synaptics driver for X 
to get the single/double tap features. I'm using Debian so I just 
installed the xfree86-driver-synaptics package, but you can download the 
source here: http://w1.894.telia.com/~u89404340/touchpad/

My configuration section in XF86Config-4 looks like:

Section "InputDevice"
   Driver        "synaptics"
   Identifier    "TouchPad"
   Option        "CorePointer"
   Option        "Device"        "/dev/psaux"
   Option        "Protocol"      "auto-dev"
   Option        "LeftEdge"      "1900"
   Option        "RightEdge"     "5400"
   Option        "TopEdge"       "1900"
   Option        "BottomEdge"    "4000"
   Option        "FingerLow"     "25"
   Option        "FingerHigh"    "30"
   Option        "MaxTapTime"    "180"
   Option        "MaxTapMove"    "220"
   Option        "VertScrollDelta" "100"
   Option        "MinSpeed"      "0.02"
   Option        "MaxSpeed"      "0.18"
   Option        "AccelFactor" "0.0010"
   Option        "SHMConfig"     "on"
#  Option       "Repeater"      "/dev/ps2mouse"
EndSection

There is also a relevant Load Module section for the synaptics driver 
and it is included as the CorePointer device so need specifying in the 
Server section.

HTH,
