Hi Mathias,

It is currently running 

FreeBSD newsplash.akips.com 12.0-CURRENT FreeBSD 12.0-CURRENT #5 86963c42c2d(drm-next): Mon Aug 14 04:26:19 AEST 2017     root at newsplash.akips.com:/usr/obj/home/src/sys/GENERIC  amd64

I tried loading the chromebook_platform.ko.  It loaded ok, but no messages.

	Paul.
