I think you must have misunderstood. Last time I worked on ATI, there was a single ROM image that supported several (maybe even all) of their addin cards. There's nothing magical about them... But that's beside the point. They may have hardcoded information about how a particular board is wired up--it's ok to use that (makes the DAC discovery much easier). We just want to avoid relying on the VBIOS for DAC setup and output probing, since we'll need to do that ourselves for suspend resume and to fully support various multihead configurations.
