Sorry, I can't quite understand what the problem is.  What are CSAB and
CSAD?  Is CSAB another bus (PCI?) containing CSAD?  A devinfo of this box
would help me understand the hierarchy.

You can always create your own _PRT entry under CSAB and compile a custom
AML.  See the acpi debugging section of the handbook for info.
