I said you have to either:

1) Use the DSDT, with a dynamic _STA method.

2) Use the SSDT, and only add the device if the device is specified on
the command line.  This avoids the avoid migration issues.  At this
point the _STA method can be static.

Using the DSDT is possible, it's just that you have to do it as well for
Q35, and I think it is harder than moving it back to the SSDT.  Sorry
for not thinking earlier about the different chipsets.
