Had the same problem (albeit with a Gentoo installation, but that shouldn't make much of a difference), and found this workaround:

You can solve it by forcing the IMPS protocol for your pointer devices, but you lose multi-touch features in the process. So you add

psmouse.proto=imps

to the kernel command line (if the psmouse driver is built as a module,
you should be able to handle this by an entry in /etc/modprobe.d/
instead) and create a file '/etc/X11/xorg.conf.d/33-input.conf':

Section "InputClass"
 Identifier "Touchpad/TrackPoint"
 MatchProduct "PS/2 Synaptics TouchPad"
 MatchDriver "evdev"
 Option "EmulateWheel" "1"
 Option "EmulateWheelButton" "2"
 Option "Emulate3Buttons" "0"
 Option "XAxisMapping" "6 7"
 Option "YAcisMapping" "4 5"
EndSection

  New

Bug description:
  I have a T450s that has the physical buttons.

  The physical buttons behave thus:

  left button scrolls up
