Are there any BIOS SETUP options for enabling/disabling ACPI?

Does any other version of Linux, or any other OS find ACPI support?
does "acpidump" run as root output anything?

I couldn't follow your link to the BIOS manual, but if there
are some docs on this system that could tell us what the
hardware is and if it is supposed to suport ACPI or not,
that would be a clue.

thanks,
