Testing On Macbook on enbug.org

re: http://grub.enbug.org/TestingOnMacbook

I am wondering who the author of this page is, and if it's possible to get a more clear step by step of how a Macbook Pro 4,1 – one of the testing configurations on that page – was configured to successfully boot Linux in EFI native mode. So far I have been unable to reproduce it based on the information provided on that page, and have found no other guides or resources indicating it's possible.

See Ben Skaggs take on this "I think you'll find the binary driver will also fail in this case with "NVRM: failed to copy vbios to system memory". Unless there's some other magic way of retrieving the VBIOS image on these machines, there's not a lot we can do."

An advantage of GRUB2 here is the ability to use loadbios. But I have not been successful at getting this to work as described.

Basically this problem blocks Live CD's from natively EFI booting a large class of EFI supporting hardware. But even if it's not possible to get this to work with Live CD, it would be nice if a clear step by step were documented with best practice to get this working after a e.g. text only installation (under EFI native booting) were performed.
