You are absolutly correct. I ran

Where did I go wrong during the install from the Ubuntu Live DVD?
Well here is where I went wrong for those that follow in my path.
I booted using the Ubuntu 12.10 Alternitive Mac x64 CD which doesn't have EFI boot support. How can you tell you ask? Boot Macbok pro by holding alt (option) key and you will get the boot menu (EFI Boot & Windows with Hard Drive Logos in mycase as I have OS X and Windows 7 with refit EFI Manger install) . Insert Alternative CD and all you will see added to boot menu is Windows with CDROM logo. Eject Alternative CD and insert Ubuntu 12.10 x64 desktop cd and you will get new CDrom Icons labeled Windows and a EFI boot. This is where the catch 22 comes into play. If I boot from the non Mac alternitive cd Ubuntu crashes with
but I can press e during grub boot and add and have the 9600M GT power down and not get the black screen as the cd boots while until the Brodcom driver crashes. So with the help above we now have both video cards avalible to grub which is what I have been after all along. No just have to figure out how to install ubuntu in UEFI or to convert existing bios install to EUFI install
b43-phy0 ERROR: Firmware file "b43/ucode16_mimo.fw" not found
b43-phy0 ERROR: Firmware file "b43-open/ucode16_mimo.fw" not found
So the question is how do I boot in UEFI mode using the alternitive Mac cd so I don't crash on the broadcom driverload.
For those of you booting from the alternative cd in bios mode and getting a black screen you have to press a key when you see the keyboard and circle icon then press F6 select "nomodeset" press enter, press esc, press enter to boot.
So I installed in Bios mode now so lets try to convert grub to UEFI mode.
I followed instructions here. https://help.ubuntu.com/community/UE..._into_EFI_mode
but now when I boot Linux I boot in to grub rescue with error /boot/grub/i386-pc/normal.mod looking at the filesystem I see now it should be /boot/grub/x86_64-efi/normol.mod just have to figure out how to make that change.
Still no love for the Macbook Pro 5,1 but still a couple more hours before bed time so maybe I will figure it out yet.
