try this and see what it shows:
grep -v adfasd /sys/module/*/parameters/si_support
/sys/module/amdgpu/parameters/si_support:0
/sys/module/radeon/parameters/si_support:1
/sys/module/*/parameters/cik_support
As root:
-bash: /sys/module/amdgpu/parameters/cik_support: Permission denied
And I checked:
# cat /etc/modprobe.d/enable_amdgpu_disable_radeon.conf
options amdgpu si_support=1
options amdgpu cik_support=1
options radeon si_support=0
options radeon cik_support=0
to verify that radeon is disabled and amdgpu is enabled.
I tried on mine, an my amd gpu is a really old one while claiming to
be supported by amdgpu, acts like it is not.

Finally did this:
I did not make the change when I got back to my office/home, and things
worked fine into mid-sunday when it locked again. Did a dnf update from
a character session after power cycle and new kernel, firefox, and
linuxfirmware. So decided to see how it would go.
And I could work with cnn and youtube and other video stuff that was
locking me up. Plus other apps, so I thought maybe things were fixed....
But twice my session aborted without a system lockup and I had to log
back in and restart everything.
Then I got a lock up again, so I power cycled and hay! New kernel. But
I still did as you instructed below, making the file and running
dracut. Now on reboot:
# lspci -nnk | egrep -i "VGA|DISPLAY" -A3
00:01.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.
[AMD/ATI] Kabini [Radeon HD 8330] [1002:9832]
Subsystem: Lenovo Device [17aa:2219]
Kernel driver in use: radeon
Kernel modules: radeon, amdgpu
which is the same as before:
It still says using radeon driver?
Should I try your radeon_blacklist.conf ?

I do not believe anything else is needed. Where dmesg said
"radeon:", it should now say "amdgpu:". amdgpu seems to be the
replacement and/or currently developed driver. And the recent
non-ryzen AMD laptops are using an older AMD cpu + ATI/AMD build-in
video, that originally were blocked from using the (at the time - )
experimental amdgpu driver.
It seems pretty likely that there is code from the radeon driver in
the amdgpu driver, a lot of the messages from it look
similar/identical, and on my ryzen system that default uses amdgpu.

Is it correct to assume that I don't have to install anything more to
get the amdgpu driver?

That will not work.
If I am reading the module options right (and other peoples comments),
amdgpu will not manage a si/cik chipset unless the correct _support is
set to 1.

The notes I found say to create a file in /etc/modprobe.d
And say call it anything but something like
enable_amdgpu_disable_radeon.conf and put this in it:
options amdgpu si_support=1
options amdgpu cik_support=1
options radeon si_support=0
options radeon cik_support=0
and then do a "dracut --force" and reboot.
The other option is to make a file called radeon-blacklist.conf and put in:
blacklist radeon
The filenames don't actually matter as long as they end in ".conf".
