Please recompile and test acpidump by running acpidump -t.  Also, it might
be nice to test it on systems with acpi disabled[*] since I think this
should work now.


* Disabled in FreeBSD, not in the BIOS.  It is not possible to run
acpidump on a machine with ACPI disabled in the BIOS since the tables will
not be present.
