The rationale of this change was to explicitly prevent these old systems
from loading ACPI. This way majority of the hard BIOS bugs can be ruled
out. With this change we follow Microsoft (ACPI was enabled by default in
Windows XP) and Linux (ACPI is disabled for systems that have been
manufactured before Windows XP).
