Hi,

I think that this was caused by the following spec changes.
From CHANGES.txt:
----
22 October 2002.  Summary of changes for version 20021022.

1) ACPI CA Core Subsystem:

Implemented a restriction on the Scope operator that the
target must already exist in the namespace at the time the
operator is encountered (during table load or method
execution).  In other words, forward references are not
allowed and Scope() cannot create a new object. This changes
the previous behavior where the interpreter would create the
name if not found.  This new behavior correctly enables the
search-to-root algorithm during namespace lookup of the target
name.  Because of this upsearch, this fixes the known Compaq
_SB_.OKEC problem and makes both the AML interpreter and iASL
compiler compatible with other ACPI implementations.

Could you send your acpidump output to this acpi-jp ML?

Thanks
