Comment 69 for bug 774089

Is there any safe way to install Ubuntu on these Macs now? Has anyone found a way to do the install that doesn't result in the firmware being re-installed (I know that once it has been done once it happens automatically the next time, but I'm not altogether sure that's a good thing either!)

Surely we need to find a solution to do the install without needing the firmware updated - why does the installer even touch the firmware?!
