I have one answer and one question. I have a MB 6,1 and I installed Ubuntu 11.04 two times. rEfit, during boot, shows two icons for the ubuntu cd: "efi install" and "linux icon". The first one is the origin of the problem we are discussing, the second one installs ubuntu in a BIOS emulation mode,without problem for me. So I think the problem is how to a MB (or MBP) decides by itself which way it wants, without rEfit. It seems that a bootable flash drive uses only Efi install.
My question is: in order to solve the problem of the corrupted firmware can I try to put the MB 7,1 EFI firmware on my 6,1? (And if it will fail, does the Matteo M. (manlbox) procedure (#111) work in any case?)
