Hi,
As I thought, a simple addition to acpi/dsdt.c and the Mac mini is able
to boot. I used the external hard drive from a fresh 6.2-install on
another computer to that purpose. This patch is tested (tried to compile
the release under the newly built kernel) and was made against 6.2-release.
I attach the patch and the dmesg-output of the Mac mini running with the
patched kernel.
Can you merge it in -current?

PS: I still fail to build the full release and, thus, also the
install62.fs image I want to use for installation. So it would be great
if you consider fixing the issue soon.
Best wishes, *Kristian
