I appreciate your work. What we need to do though is remove acpidump(8)
from the system and import Intel's acpidmp utility. It's included in the
ACPI-CA distribution and is functional enough that we can use it.

Any functions we need that it doesn't yet have can be submitted to Intel
to merge.

Thanks,
