ACPI Requirements Firmware

Hi everyone,
I am current looking for what ACPI Tables are required in order to support NVIDIA graphic cards firmware-wise? I am working for an Independent BIOS Vendor, and we are trying to add support for NVIDIA graphics card. Unfortunately, I can not find any requirements for the firmware to support it.

Can someone help me out here?

Did you get a contact?

Nope - do you have a contact for me?
