drm-*-kmod port for Comet Lake

[Kevin Oberman]

I have a new laptop, a ThinkPak L15 with a Comet Lake processor. I quickly
discovered that 12.1 didn't know anything about it, so I reinstalled from
head. Now I need to install the proper kmod and I'm not sure whether I can
use current or if I need devel.

Based on the latest DRM update, I'm pretty sure one of them supports Comet
Lake, but I'm nor sure I can use current orm even if I can, if devel is at
a point where I should just go with it as it sounds like it will soon be
"current".

Or, am I really in trouble and Comet Lake I simply not supported at all?
The symptoms make me suspicious that the device is simply not recognized.

Running current from 9/3 snapshot and latest ports all installed from
packages.
