Right, I believe xf86-input-synaptics only works with psm(4).

Sounds like moused(8) drives the Trackpoint, if it quit working after
disabling moused.

What are the outputs of the following commands:

 1) dmesg | grep psm
 2) grep -C 5 -i '\(ps/2\|synaptics\)' /var/log/Xorg.0.log    # in the
"touchpad working perfectly" configuration
 3) ps axww | grep -v grep | grep moused       # in the "trackpoint
working perfectly" configuration

It might be useful to see /all/ of /var/log/Xorg.0.log, not just the
Synaptics and PS/2 lines....
