Macbook Air 4.2 : Synaptics refuses to load

I can't quite seem to get my synaptics to load as a device driver for my touchpad. Each time, it unloads itself with the following errors :

[  2708.893] (--) Apple Inc. Apple Internal Keyboard / Trackpad: no supported touchpad found
[  2708.893] (EE) Apple Inc. Apple Internal Keyboard / Trackpad Unable to query/initialize Synaptics hardware.

Took a little while, but I've finally managed to get my Synaptics driver loading consistently for my touchpad :
/etc/X11/xorg.conf.d/10-synaptics.conf

Section "InputClass"
  Identifier "touchpad catchall"
  Driver "synaptics"
  # Note : MatchIsTouchpad "on" wouldn't give me squat
  MatchIsKeyboard "off"
  MatchProduct "Apple Internal Keyboard"
  MatchDevicePath "/dev/input/event*"
<snip>
EndSection

I've double checked my touchpad input device :

cat /proc/bus/input/devices | grep mouse
sudo cat /dev/input/event6

I've tried both the standard synaptics driver as well as the xf86-input-synaptics-clickpad and both have the same result. Essentially Synaptics loads, doesn't like my touchpad and commits suicide :
