I have a set of older machines (e.g. AMD Phenom II, Radeon HD3300

One system is being done now, to allow time to catch any major
problems and then plan the update process.
Looking at src/UPDATING, the only thing I don't understand is the
whole drm-kmod change. Is there an authoritative write-up on what's
going on, how to choose the right drivers for my hardware, and how to
do this from source without forcing a fresh install?
We are working on better documentation for this, but the main highlights
are: In most cases graphics/drm-kmod should suffice, especially on
somewhat modern hardware. You can also install any of the drm-*-kmod
ports directly, if you want a specific version. In general graphics
hardware older than from 2013 requires drm-legacy-kmod instead.
drm-kmod will also install drm-legacy-kmod on i386.
The same drivers in drm-legacy-kmod is also available in base on 12, so
you can use the base drivers. This is deprecated however, and not the
case for 13-CURRENT.
You can install the drivers either from pkg, if you are using the
GENERIC kernel, or build from ports if you have a customized kernel or
if you are tracking for instance 12-STABLE or 13-CURRENT.
If you are using drm-legacy-kmod or the base driver with AMD graphics
cards you might also need to install xf86-video-ati-legacy rather than
xf86-video-ati.
