Nice. Please add debug.psm.loglevel=3D5 line to /boot/loader.conf,

reboot, than try move pointer with trackpoint in up-left and down-right
directions,

and than copy psm packet log from dmesg buffer to a file and attach it
to PR/238291.

packet log looks like that:


psmintr: 80 00 00 c0 00 00

psmintr: 80 00 00 c0 00 00

psmintr: 80 00 00 c0 00 00

psmintr: 90 dd 32 c0 05 31

synaptics: ipacket: [3333, 3377], 50, 4

synaptics: ----

Its better although not strictly necessary to have patch from my
previous email applied.
