One step closer on booting Ubuntu Live from USB on the Santa Rosa MacBook Pro (MacBookPro3,1):
If you format the USB device with FAT16 and put the following file there, exactly in this place and with this name /efi/boot/bootx64.efi then a reboot with the Alt key pressed *does* show the USB device as a bootable device and there is a new icon in rEFIt for booting the /efi/boot/bootx64.efi. In theory, we should be able to use any x86_64(!) EFI application as the bootx64.efi file. In practice, I don't know whether there is a working EFI application that can successfully boot Ubuntu from USB. I tried 64-bit ELILO from http://downloads.sourceforge.net/elilo/elilo-3.8-x86_64.efi and I got an elilo prompt when I selected the new "boot /efi/boot/bootx64.efi from usb" entry in rEFIt. At this prompt, I can enter exactly 1 character (which is shown on the screen), but then the keyboard freezes. When I add a /efi/boot/elilo.conf file and specify a kernel and initrd to load, then elilo does try to load them. So elilo can definitely read from USB via EFI on the MBP. However, it then displays an error message mentioning "system.c" for a millisecond and then immediately reboots. grub-efi is another EFI boot loader, but apparently grub-mkimage only creates an 32-bit efi file (even on 64-bit Ubuntu) whereas the MBP3,1 needs a x86_64 binary.
