Maybe you've sorted it out already, but I got natural scrolling to work by using the x11 in ravenports
And then just as with your current setup /raven/etc/X11/xorg.conf.d/00_scroll.conf: Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/sysmouse" Option "ZAxisMapping" "5 4" EndSection
