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.
