If the D6430 is any indication, it seems the driver likely only checks
the DSDT. Are you certain you modified this correctly to reflect your
machine? You'll need to carefully compare the DSDT of your machine and
that of Qemu. Given that James was the one to initially crack this one,
he might have some more concrete advice.
