Comment 71 for bug 898784

I'd like to be wrong and see this work, but I remain suspicious that this is Apple's responsibility to provide adequate hardware information in their CSM BIOS, which they may not, therefore nouveau can't do the right thing. Or Apple needs to move to a standard implementation of UEFI with UEFI drivers which they may not be able to do depending on their licensing with Nvidea, or their own priorities - running anything other than Mac OS on Apple hardware I perceive to be a rather low priority for Apple. They tend to do the minimum required.

But it's an interesting point that the CSM BIOS is adequate for Windows Vista and 7 to get the necessary information in order to support this same hardware. *shrug*
