Um mir mal kurz selber zu Antworten:
Unter Ubuntu konnte ich das Touchpad mit gpointing-device-settings deaktivieren, unter Arch tun allerdings die Einstellungsmöglichkeiten bezüglich Touchpad dort einfach nicht.
Noch einige Konsolen-Ausgaben:
nano-laptop nano # xinput list

⎣ Virtual core keyboard id=3 [master keyboard (2)]

und sollten touchpad bzw. trackpoint deaktivieren, jedoch zeigen beide keinerlei Reaktionen auf diese Befehle.
