thus is not comaptible with Xorg Synaptics driver.

+ This driver supports Synaptics I2C touchpad controller on eXeda
+ mobile device.
+ The device will not work the synaptics X11 driver because
+ (i) it reports only relative coordinates and has no capabilities
+ to report absolute coordinates
+ (ii) the eXeda device itself uses Xfbdev as X Server and it does
+ not allow using xf86-input-* drivers.
+
+ Say y here if you have eXeda device and want to use a Synaptics
+ I2C Touchpad.
+
+ To compile this driver as a module, choose M here: the
+ module will be called synaptics_i2c.
