Acer C720 - lingering touchpad issue after patches

Appreciate all the work the community has put into this.  I chose Arch for running my new C720 and I'm quite happy with the choice so far despite never having used it previously.  I'm posting this from my Arch/C720 as I speak so - so far so good.  :)

I do have a lingering issue with my touchpad.  I have applied the patches - using the scripts and also manually by following the script's lead.  I believe I have the drivers working correctly because I can get dd output from /dev/input/event11 which is what Xorg reports corresponding to cyapa.

Including the relevant part of Xorg.0.log.  Happy to provide more if it's helpful.  Thanks in advance for any help I receive.

So what is your lingering issue, I don't quite follow?

Re: Acer C720 - lingering touchpad issue after patches

Sorry I wasn't clear.  The touchpad wasn't working in X at all despite seeing dev activity via dd.  I had 32-bit Arch installed and since then I've switched to 64-bit.  Now all is well.  Either the issue is specific to 32-bit or (more likely) it was something that I did wrong during installation/configuration.  Thanks for the response, though.
