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.
