Can one disable tap-to-click in X server configuration, without synclient?

I want to configure my system so that tap-to-click is disabled on the touchpad. (It's running a rather old version of ALTLinux distro with xorg-server-1.4.2-alt10.M41.1.) The most popular [advice](https://askubuntu.com/a/166407/19753) I have found is to execute synclient MaxTapTime=0 in the user's X session. I could accept this solution, but the problem is that this doesn't work for all users with their different preferred X "environment". The first user has logged in in the linux console, and run startx. X server for his session has occupied the 7th virtual linux console. He uses bare ratpoison. The second user has logged in, run startx. X server for his session has occupied the 8th virtual linux console. He uses WindowMaker. synclient MaxTapTime=0 has had an effect in the second user's X session, but has had no effect when executed in the first user's X session. So, can this setting be done system-wide, for the X server, perhaps in xorg.conf?
