I haven't seen anymore discussion on this, did we ever get the 4890 flashed and working as a native card in a mac pro? I'd really like to buy one and do this, I know there is the natit fix but that is a no-go for me as I need the boot screen on my mac. I also need dual DVI ports as I have dual 23" cinemas. Does anyone have anymore information on this? Are we making any progress on why the flash for the 4870 doesn't work with dual DVI ports on anything but the XFX card? Thanks for everything!
