With thanks to huyz for the notification – there is now a patch from baryonix available for VMware 15.5.6 and Kernel 5.8..    The patch is available here:  https://github.com/baryonix/vmware-host-modules/tree/fixes-for-5.8

I have – briefly – tested this with Kernel 5.8.5, and it was successful..     As the usual # vmware and # vmware-modconfig still segfault, then vmmon/vmnet have to be installed from the patch fileset, after compilation.    VMware can be started by # /usr/lib/vmware/bin/vmware

I have also tested it with Kernel 5.9-rc3 and – so far – it seems to work OK..
