The Handbook chapter describes what to do:

No.  Please don't use that, it's not necessary and sometimes causes 
problems.  AutoAddDevices "Off" by itself disables hal input device

Or just put them in ServerLayout.

I think that DontZap is back to the default, but it's now the key 
combination that is unset, so setxkbmap -option terminate:ctrl_alt_bksp 
is the way to fix it.  But it's been a while since I've needed to kill 
X manually, so haven't tried it lately.
