For Synaptics touchpads, set the 'Synaptics Scrolling Distance' property to a pair of negative values (like -100 -100).
For devices that have the 'Evdev Wheel Emulation Axes'property , set that to '7 6 5 4'.
For regular mice with an actual scroll wheel, no idea.
Doing the equivalent of all this using just one line in .Xmodmap was definitely more convenient (not to mention more robust: any devices you would plug in at run time would scroll right without having to configure them specially), but I guess progress happens.

If it's an xorg.conf option as well, then you can use an InputClass snippet in xorg.conf.d to automatically apply it to all devices, or only a certain subset of devices, or, or.
