Many thanks for all the information and suggestions.
At present I don't have time, and probably lack the expertise to search
for, compile if necssary, install, etc. any non-Redhat/fedora kernel, so I
am inclined to wait to see how Redhat/Fedora get on with the new intel
cpus.
If there's no progress in the near future, probably the first thing I
should try is to get the kernel packages from Intel's Clear Linux
https://clearlinux.org/
since I already know from a test a few days ago on a 'live' usb drive that
Clear linux definitely can run on my new PC with full resolution.
Another option could be to install clear linux in its own partition and
then try to install my standard tools (e.g. ctwm, poplog, libreoffice,
fetchmail, vlc, and many more) on that. But that could be very time
consuming.
If I get time to investigate, there may even be a way to copy core parts of
the clear linux directory tree into my fedora partition, I already have
several non-fedora packages (e.g. ctwm) in a separate 'local' subtree,
which could perhaps be accessed either when fedora is running or when clear
is running.
But if I have to duplicate all the construction (e.g. rebuild ctwm for
Clear) that will be too much hassle.
I am grateful for the suggestions, but did not intend to hijack the ctwm
list for this!

PS
As an afterthought I've just searched for and found this:
https://repos.fedorapeople.org/repos/thl/kernel-vanilla-mainline/fedora-33/SRPMS/
It provides
kernel-5.8.0-0.rc6.20200723gitd15be546031c.1.vanilla.1.fc33.src.rpm
I think it should be usable with fedora 32 non-kernel and non-fedora
packages.
There are also suggestions there that I had not found previously. So I'll
explore suggestions that keep me within fedora for the present. I won't
bother this list with details except to report success or failure later!
