Going to 64-bit PV avoids your problem but I'm not convinced that
the kernel is the cause of your problem.

I am running 4.14 hypervisor (self-compiled) and it has capability
xen-3.0-x86_32p and does still run 32-bit PV with domU kernel versions < 5.10.

So I do not think we have got to the bottom of why your hypervisor
does not have that capability and why it can't boot Debian buster or
previous domU.

As far as I am aware, the hypervisor only drops xen-3.0-x86_32p
capability from version 4.15 onwards.

You may want to ask on Debian's Xen team mailing list:
