It seems to be unavoidable as soon as you want to install a
desktop environment (Gnome, KDE, Xfce, LXDE). But X itself
works fine without HAL, so do lots of window managers and
application programs. HAL seems to be abandoned in Linux land,
but still many GUI ports make it a dependency... :-/

Depends. Especially if you haven't entered X yet, it seems to
be possible. However, a clean reboot is usually the better way.
For this to work, it's neccessary (!) that no further references
to such kernel modules exist in any of the relevant configuration

It's a dependency of the i915kms module. I have a laptop that
runs FreeBSD 12.0-p7 where I have in /boot/loader.conf:
And then kldstat reports drm2.ko to be loaded as well.

Technically, it doesn't seem to matter, as only the point in
time is affected when the module is loaded. Manually loading
it and then using this as a starting point for further experiments
with X is okay.
Also see my note above - it also seems to work when loaded
There was also a case where "manually" executing "kldload <something>"
was required in /etc/rc.local. :-)

Exactly. That's why any existing configuration file should be
removed, just to be sure. X can generate one if needed, but in
most cases, it's _not_ needed. Sometimes you only need a
partial file in /usr/local/etc/X11/xorg.conf.d/ to regulate
a specific aspect of X, like keyboard settings or s forced

In this case, knowing the exact hardware configuration is
neccessary. FreeBSD system tools can provide this information,
and it needs to be reflected by the kernel modules loaded,
the X11 drivers installed, and what X detects (checked with
the log file).
It isn't that complicated. ;-)
