Problem Description:

The Linux kernel ACPI interpreter fails the following
AML test when it is compiled into a simulator. So if an
OEM BIOS includes this code, Linux would fail.

Steps to reproduce:

Run interpreter with the .asl demo code attached below.

ASL code to reproduce bug.

The Write access automatic dereference allows to apply the write
operations from inside the Method to the initial object passed to
that Method as a reference to the object (but not the object itself)
and referred to by argx from inside that Method (initial object is
changed).

In case a passed to Method reference is obtained by the
Index operation this feature doesn't work, but should.
Demo reports improper behaviour as "Error N", "Ok N"
otherwise.
