I believe that this problem may be fixed in ACPICA version 20080213:


13 February 2008. Summary of changes for version 20080213:


commit 24a3157a90ddf851a0880c0b8963bc43481cd85b
Author: Bob Moore <robert.moore at intel.com>
Date:   Thu Apr 10 19:06:43 2008 +0400

    ACPICA: Fix for possible error when packages/buffers are passed to meth=
ods externally

    Fixed a problem where buffer and package objects passed as
    arguments to a control method via the external AcpiEvaluateObject
    interface could cause an AE_AML_INTERNAL exception depending on the
    order and type of operators executed by the target control method.
