Is this a pci-e card? With a pci-e card, the actual chipset type is located
in one of the registers (instead of deriving it from the pci device id) and
will resolve into one of the supported architectures, usually an NV_ARCH_40.
Can you try this patch instead? And send me your dmesg whether it works or
not.
Thanks.
