Brightness on Thinkpad X1 Carbon 6th gen without X/DM/WM

I've run Arch on a RPi but this is the first time trying to use it as my main machine and I'm slowly getting things going with lots of wiki reading (thanks everyone for all the work there!).
I'm wondering how/if I can get the brightness keys to work without X (so no Xbindkeys).

The following works and I'm able to change the brightness (as root).

tee /sys/class/backlight/intel_backlight/brightness <<< [NUM BETWEEN 0-1060]

I've tried setting the following kernel variables separately to get the brightness buttons to control this to no avail:

acpi_osi="!Windows 2012"
acpi_backlight=vendor
acpi_backlight=native
acpi_brightness=vendor

Anyone else have an X1 Carbon 6th gen with the brightness buttons working in the virtual console?
