How to fix an incorrect SubSystem ID value?

My graphics is (apparently) reporting an incorrect SubSystem ID value, which causes it to be reported incorrectly in some software.  Specifically, it's a mobile FirePro M5100, being reported as "AMD Radeon R9 M200X Series", probably because it has identical Device ID as an R9 M270X (which is by design, these are supposed to have the same Vendor ID, but not the same SubSystem ID).  I'm experience a few glitches in various gpu-intensive software (details if you need), and I think the incorrect device reporting is to blame.


The problem started after I swapped my GPU from a FirePro M5950 to the newer M5100 (newer, despite the lower model number).  Swapping is possible because my laptop has an MXM Type A slot.  But now, it's reporting the old SubSystem ID of 04A3, instead of the correct value which I believe is 15CC.

This is maybe a problem with ACPI tables?  But I don't know how to fix that.  Any ideas how to fix this?


Help is much appreciated!
