You will need a v4.11-rc1 at least for those buttons to be reported.

Dmitry made a respin of them with a saner approach. Unfortunately, the
touchpad doesn't respond correctly when psmouse is compiled in the
bzImage, so I am still investigating that. So we are hopefully going to
see this merged soon. (Looking at your dmesg let me think that psmouse
is compiled at a separate module in your case, feel free to test the
new series: http://www.spinics.net/lists/linux-input/msg50162.html )

Cheers,
