again, thx.
Building world and the kernel worked, I'm now running that kernel I built.
I managed to successfully build graphics/drm-devel-kmod and
gpu-firmware-kmod. "make install" for some reason didn't - I could only
find modified amdgpu.ko in graphics/drm-devel-kmod/work/stage/boot/modules/
(and no documentation on how to achieve this) - so I copied all the .ko
files from that directory into /boot/modules, though a reboot didn't help,
here's the latest Xorg.0.log output (selected)

[    22.733] (==) Matched ati as autoconfigured driver 0
[    22.733] (==) Matched modesetting as autoconfigured driver 1
[    22.733] (==) Matched scfb as autoconfigured driver 2

[    22.747] (WW) VGA arbiter: cannot open kernel arbiter, no multi-card

[    22.747] (EE) Screen 0 deleted because of no matching config section.

and indeed, /dev/dri is nonexistent (though /dev/drm/ contains a ton (...
ok, 0x100) of driver entries). Also note: amdgpu appears nowhere in the
excerpt above (or even the complete Xorg.0.log file).

One thing I remember from the previous ghostbsd installation:
/etc/rc.conf's kld_list contained a few more entries that just
"/boot/modules/amdgpu.ko" that I have now ... should I put something else
in?

so - once more - I'm hoping for your guidance :-)

thx
Michael
