This means it would often discover a 0 year and then turn off ACPI because it thought the BIOS was too old. Some systems don't boot without ACPI so this was a problem. I have a full fix by adding new very early DMI detection, but it needs more testing before it can be merged. For 2.6.16 let's just turn the check off. It never made much sense anyways because there are no x86-64 systems older than 2002 or so and they generally all have working ACPI.
