And some more digging... The normal synaptics loading rule in the xorg conf files wasn't being triggered as the "matchIsTouchpad" was failing. I tried adding an explicit driver association to the relevant input device, and setting the protocol to "event".
This failed like so: (from /var/log/Xorg.0.log) [ 10517.611] (II) LoadModule: "synaptics" [ 10517.611] (II) Loading /usr/lib/xorg/modules/input/synaptics_drv.so [ 10517.611] (II) Module synaptics: vendor="X.Org Foundation" [ 10517.611] compiled for 1.15.0, module version = 1.7.4 [ 10517.611] Module class: X.Org XInput Driver [ 10517.611] ABI class: X.Org XInput driver, version 20.0 [ 10517.611] (II) Using input driver 'synaptics' for 'USB Keyboard+SmartPad' [ 10517.611] (**) USB Keyboard+SmartPad: always reports core events [ 10517.611] (**) Option "Protocol" "event" [ 10517.611] (**) Option "Device" "/dev/input/event13" [ 10517.611] (--) synaptics: USB Keyboard+SmartPad: Vendor 0x4f3 Product 0x740 [ 10517.611] (--) synaptics: USB Keyboard+SmartPad: invalid x-axis range. defaulting to 1615 - 5685 [ 10517.611] (--) synaptics: USB Keyboard+SmartPad: invalid y-axis range. defaulting to 1729 - 4171 [ 10517.611] (--) synaptics: USB Keyboard+SmartPad: invalid pressure range. defaulting to 0 - 255 [ 10517.611] (--) synaptics: USB Keyboard+SmartPad: invalid finger width range. defaulting to 0 - 15 [ 10517.611] (--) synaptics: USB Keyboard+SmartPad: no supported touchpad found [ 10517.611] (EE) synaptics: USB Keyboard+SmartPad: Unable to query/initialize Synaptics hardware.
