Yes, the next kernel version probably will have this config change
applied. Just needs to check if it doesn't break anything (for example
installer).

As you've probably seen, I've also created rpm packaging of it. This way
it would be trivial to install the package out of yum repository (for
now - "qubes-dom0-unstable").

So, now the installation instruction would be:
sudo qubes-dom0-update --enablerepo=qubes-dom0-unstable
kernel-4.1.13-8.1* kernel-devel-4.1.13-8.1* psmouse-byd-dkms

There are also some (minor?) issues with the driver itself (cc Jay Kuri
for that):
1. There are kernel messages about "unknown code detected". I've noticed
those:
 - d7, 29 - no idea what was that
 - 32 - two-finger click
 - ce - three-finger click
 - 2f - two-finger click at the bottom edge
2. Haven't managed to get middle-click in any way
3. Not possible (?) to re-enable touch-to-click (but disabled by default
   seems to be ok)
