this one isn't available on all pointing sticks, looks like yours is one of
them. The crashes are a systemd issue, would be worth filing a bug for that.
Errors are ok, but this shouldn't segfault. 



as for CONST_ACCEL: this is applied by libinput directly and it shows up in the
log above 

[  1090.182] (II) Device 'Elantech PS/2 TrackPoint' set to const accel 100.00

however, setting it to 100 may just trigger some unrelated bug, I very much
doubt you'd want the pointer to move 100 pixels each time you generate a single
1unit movement from the trackpoint. set it something more tame like 1.5 or 2
and see how you go with that first.
