The earliest machines that have ACPI are in the Pentium 200 range.
The last of the original P54C family. I have one really old laptop
that has a "mobile" Pentium 300 in it that has ACPI, but its bios is
too old to use. This is on the cusp of the Pentium II class machines,
so I think we'll likely be OK. Newer enough versions of the BIOS just
aren't available for these older machines that I've been able to find.
