Dynamic SSDT's are loaded from OpRegions by address.

If you want to change the AML in those opregions,
you have to acquire it with acpidump --addr xy.
That is true no mater what override scheme you're using.

However, if you don't want to modify the dynamic SSDT,
then it does not have to be dumped -- it will continue
to be accessed via Load() of the opregion; and it
is totally unrelated to a DSDT or a DSDT+static-SSDT override.

I am doubtful that SSDT override support past what
we have already justifies its own complexity.
