Ok. Well, I've put all of the "seems to be associated" kexts, plugins and bundles into one dir so I can keep track of what I'm doing. I don't have this particular card so I can't do much more than go through all of the plists and see if one is associated with the other. I've extracted all of the actual driver portions out of each one. binwalk isn't an option for me on os x till I can get the problems with libmagic sorted out, refuses to compile. Once I get that sorted, I'll post all of the firmware dumps that I can get out of the drivers and maybe we can start sorting this out. I did find several points along the way while browsing that show which parts are associated with framebuffer relating to open firmware and what seems to be a portion in the driver that has the human readable console output if you were loading with -v for os x. I see things about "found card, loading framebuffer device". Granted that could just be for the verbose console output before the gui loads. I wish I had the actual card, but there isn't one available close to my residence. You or Justin mentioned it not working on linux and while searching I did find some posts on debians mailing list where someone did get the card detected with the radeon driver, but it's fighting with offb and results in a white screen when X loads.
