Udev17 breaking touchpad?

Hey all,

I've tried searching here but haven't been able to find what's going on here. After installing udev17, it looks like my synaptics touchpad has stopped working. The keyboard does work fine, and so does an external mouse. I downgraded to udev16 and that fixed my issues. I've tried a few fixes I searched for on the forums but nothing seemed to point directly to what I'm experiencing.

Possibly relevant parts of logs from udev17

Re: Udev17 breaking touchpad?

I should add I've tried this fix suggested here but have not had success. That fix (changing the 10-synaptics.conf to MatchIsKeyboard=on) broke the keyboard as well..
