touchpad event keep changing after reboot

So I've been having this issue with my laptop since I got it. Whenever I reboot, the event of the touchpad keeps changing. Here are the relevant files i think. I understand the synaptics.conf file points to it being at event12, but thats because it WAS at event12 the last time i booted into arch. Anyone know of a way to lock it in place? Or any other solutions?

[    26.253] (II) config/udev: Adding input device SynPS/2 Synaptics TouchPad (/dev/input/event8)
[    26.253] (**) SynPS/2 Synaptics TouchPad: Applying InputClass "evdev touchpad catchall"
[    26.253] (**) SynPS/2 Synaptics TouchPad: always reports core events
[    26.253] (**) SynPS/2 Synaptics TouchPad: Device: "/dev/input/event8"
[    26.280] (--) SynPS/2 Synaptics TouchPad: Found 3 mouse buttons
[    26.280] (--) SynPS/2 Synaptics TouchPad: Found absolute axes

Re: touchpad event keep changing after reboot

I believe this is a udev problem similar to the swapping of disk controllers and network adapters.  This: http://wiki.archlinux.org/index.php/Ude … _Each_Boot describes how to control the order in which modules are loaded, hence the numbers they are assigned.  Otherwise, the modules are loaded asynchronously and can occur in any order -- I think...

Anyway, give it a shot, it won't hurt anything.
