efi boot, nvidia, macbookair3,1

[Trevor Jim]

Hi, I'm trying to debug nvidia graphics with EFI boot on a
MacbookAir3,1.  Any pointers would be appreciated.

EFI boots fine to console.  Black screen on xinit with nvidia driver.

I hear nouveau is the same, however, the following bug report indicates
the problem is that nouveau (and presumably nvidia) expects the bios
information in a different location than provided by grub:

Where would be the place to fix this?  fakebios/loadbios?  Not grub? :-)
