I think the most straightforward fix is for ACPI-CA to not load SSDT 
tables when the user is overriding the DSDT.  If you treat overridden 
SSDTs separately, you go down the path of having to specify _which_ 
table you want to override, which implies you need strict ordering of 
tables in both ASL and AML and it just gets too complicated.  Some HP 
Itanium machines have 8 to 10 SSDTs.
