Hi,
I have managed to extract the actual Open Firmware nVidia Quadro FX4500 PCI
expansion ROM which i have attached.

The actual ROM itself seems to have a PCIR header located @ offset 0x20.

Could it be that nouveau is actually trying to read the PCIR header directly
off the XROM (which is how i assume it would be done in x86) and not via the OF
device tree for ppc arch in the newer versions of nouveau by any chance?

Regards,
Peter
