First of all, is that true that all SSDT's are always loaded 
automatically?
ACPI 3.0 Thermal model requires SSDT dynamic loading,it seems.
(Section 11.6)

If so, it may cause trouble when all SSDT's and an original DSDT
are compounded into a DSDT.
I think ACPI-CA itself can override any SSDT by checking existing
SSDT header passed to AcpiOsTableOverride.
