I'm going to report back, but it is not a good answer (imho)...

I received the AMD Radeon RX 6600 and started installation. I removed
the NVIDIA GTX 1060 that shipped with the machine. The AMD Radeon RX
6600 has a different power connector, so it was not actually
installed. At this point, the machine only has the onboard Intel UHD
Graphics 630 available.

I figured, what the hell... Power it up and see what happens... Lo and
behold, video/graphics are back.

So it appears the machine was still trying to use the NVIDIA GTX 1060
even when the HDMI cable was plugged into the Intel UHD Graphics 630.
I also think that shifts suspicion from kernel graphics to NVIDIA
drivers.

I'm not a gamer, so I don't really need the AMD Radeon RX 6600 or the
NVIDIA GTX 1060. SuperTux plays just fine with the Intel card.
