I erred in following the steps. I copied 
5.3.18-lp152.41-default/kernel/drivers/gpu/drm/radeon/radeon.ko
as .radeon.ko41 in the .44 /kernel/drivers/gpu/drm/radeon/ directory and
5.3.18-lp152.36-default/kernel/drivers/gpu/drm/radeon/radeon.ko and as
.radeon.ko36
after renaming .44's radeon.ko .radeon.ko44.

I then proceeded without the next steps (the /extra/ directory and running %
depmod and % mkinitrd) to shutdown, swap DVI cable from DP cable, booted .44,
and all seems to be working completely normally.

I did note that radeon.ko for all of .36, .41 and .44 have the same byte count,
2,894,595. I see that .33's is 2894691.

Then I copied .33's radeon.ko to 5.3.18-lp152.44-default/extra, but '% depmod
5.3.18-lp152.44-default' reported

    bash: fg: %: no such job

My kernel last installed on this host before .44 is .20, so I suppose the
regression may be from .36.

So I'm paused to comment here.
