I made that patch a long time ago. The picked values for the horizontal
axis don't work well: you can't mix a movement on both axis in a single
event. 3/-3 would be a better choice so you can have -3+1 for example
and distinguish a movement on the vertical axis and another movement on
the horizontal axis. -2+1 would be understood as -1.

xf86-video-mouse and moused(8) shoudl ask the kernel if an horizontal
axis is supported. If the kernel doesn't know about this "horizontal
thing" xf86-video-mouse is talking about, it means it's unsupported.

I believe a more long term solution would be to test the evdev GSoC:

It would allow us to fully use xf86-video-synaptics which must be
supporting horizontal scrolling.
