firmware (e.g. bios and peripherals)
As of writing, the current bios version is 1.0.7. By visiting the downloads section (for the type HG/HF T470s) an iso can be downloaded and burned to disk which will perform the update [1]
This laptop is unique in that it retains the thinkpad dock connection as well as provides docking ability over USB-C. We have tested with the Thinkpad Ultra Dock and are able to utilize multiple HiDPI monitors via individual connections (e.g. no display port chaining). There are published firmware updates for the dock that require windows to install. DisplayPort chaining works via USB-C to DisplayPort adapter.
kernel and hardware support
Installation with modern media puts you on Kernel 4.10.10-1, however this note made linux-mainlineAUR seem essential.
As advised in Intel graphics#Enable early KMS and Kernel mode setting you can add i915 to your modules.
Hardware video acceleration with Kaby Lake seems to work fine via va-api.
On gnome-shell via wayland, suspend-resume results in the fan holding at 100% without ever spinning down. Alternatively if you use xorg this doesn't seem to happen.
mobile broadband
The mobile broadband card is a Sierra EM7455, which can be seen below in the lsusb. We have confirmed working with with Google's Project Fi.
