Issues with the new xorg-configuration

[Luther Thompson]

After last week's changes to how xorg configuration works, but I still
have some problems with the touchpad. Essentially, the extra-config
seems to have no effect.

1. The Tapping option does not work.

2. The HorizontalScrolling option does not work. Strangely, the
documentation[0] says that "HorizontalScrolling" *disables* horizontal
scrolling. I've tried it both ways.

3. The DisableWhileTyping option does not work. This actually never
worked, even before the change.

I've attached my config.scm file.
