It's not likely ACPI is supported on the box if it's that old. Even
machines that claim to support ACPI often had major problems. What's
happening is that the RSDP, which is the root pointer for ACPI, can't be
found in physmem. It's likely that you have to turn on ACPI in the BIOS
for the BIOS to install the tables. If you can't do that, then just add
hint.acpi.0.disabled="1" to your loader.conf and enable apm instead.
