Public bug reported:

Currently writing a small kernel, when trying to detect memory blocks
that contain ACPI information, no such block is found. When ran in
Oracle Virtualbox, code runs flawlessly.

Code that is detecting the ACPI-Info (with a bit of debug-output):

```
multiboot_memory_map32_t* map = (multiboot_memory_map32_t*)mmap;
for (uint32_t i = 0; i < size; i++) {
 Termutils::cout << map[i].type << "type of block  ";
        if (mmap[i].type == MULTIBOOT_MEMORY_ACPI_RECLAIMABLE) {
             Termutils::cout << "WE ARE INSIDE\n";
             fadt = (FADT*)(map[i].base_addr_low);
        }
 if (i % 9 == 0) {
  Termutils::cout << "\n";
 }
}
```

command qemu is run with:

qemu-img create build/objects/test 500M
qemu-system-i386 -hda $(APP_DIR)/clinl.iso -hdb ./build/objects/test
