Fingerprint Reader
The fingerprint reader included with this model `138a:0097 Validity Sensors, Inc` currently lacks a linux driver. Community discussion of this issue indicates that preliminary efforts to reverse engineer a driver have failed. Synaptics (which has acquired 'Validity Sensors') has unofficially said that they cannot disclose the protocol, but may possibly release a binary driver.

TrackPoint Scrolling
TrackPoint Scrolling is working out of the box in GNOME and MATE. In some WindowManagers, the TrackPoint middle-button scrolling can be enabled by installing the xorg-xinput package from the official repositories and appending the following line to your .xinitrc:
xinput set-prop "ImPS/2 Generic Wheel Mouse" "libinput Scroll Method Enabled" 0 0 1
Lenovo ThinkPad USB-C Dock
The USB-C Dock is a Thunderbolt 3 device. Plugging it in results in a whole lot of PCI entries:
06:00.0 PCI bridge: Intel Corporation JHL6540 Thunderbolt 3 Bridge (C step) [Alpine Ridge 4C 2016] (rev 02) 07:00.0 PCI bridge: Intel Corporation JHL6540 Thunderbolt 3 Bridge (C step) [Alpine Ridge 4C 2016] (rev 02) 07:01.0 PCI bridge: Intel Corporation JHL6540 Thunderbolt 3 Bridge (C step) [Alpine Ridge 4C 2016] (rev 02) 07:02.0 PCI bridge: Intel Corporation JHL6540 Thunderbolt 3 Bridge (C step) [Alpine Ridge 4C 2016] (rev 02) 07:04.0 PCI bridge: Intel Corporation JHL6540 Thunderbolt 3 Bridge (C step) [Alpine Ridge 4C 2016] (rev 02) 3c:00.0 USB controller: Intel Corporation Device 15d4 (rev 02)
It works nearly perfect out of the box with Kernel 4.10.13. The only thing that did not work is the r8152 based USB Ethernet Port, which gives the message:
[ 7.574773] r8152 4-1.1:1.0 (unnamed net_device) (uninitialized): Unknown version 0x6010
Installing r8152-dkmsAUR fixes this (the DKMS module adds the version 0x6010 to the module).
Even hot plugging works: unplugging the dock while a display is connected just lets all the devices disappear. Replugging it later works, all the USB devices come back up automagically, thought you might need to issue a xrandr to get the display showing again (tested with Xorg based i3 setup).
