The "etc/acpi/nvdimm-mem" fw_cfg blob is guaranteed not to contain ACPI tables, so turning off the ACPI SDT header probe in OVMF is the right thing to do.
SeaBIOS needs a patch for recognizing (and masking out) the BIOS_LINKER_LOADER_ALLOC_CONTENT_NOACPI bit, but its behavior will not change. Regarding the allocation zone, we cannot relax that to 64-bit, because the "MEMA" object (NVDIMM_ACPI_MEM_ADDR), into which the address of "etc/acpi/nvdimm-mem" is patched, is only a DWORD.
