If you add an ssdt or a custom_method in, say, Linux, your additional methods are limited to 32-bit address space. For example, this is invalid in current qemu: DefinitionBlock ("blah.aml", "SSDT", 2, "", "", 0x00001001) { OperationRegion (BLAH, SystemMemory, 0x1ffffffff, 1) But it becomes valid when applying this patch.
