The kernel must be booted using EFI stub booting (that's where the code for getting the bios image is). If you are already using EFI stub booting, maybe you need to add additional handling for your mac? Anyway, this isn't really a radeon driver issue per se, it's a mac platform bug. -- You are receiving this mail because: You are watching the assignee of the bug.
