This is pretty tangential to the topic, but if anybody is looking to dual- or triple-boot without resorting to third-party EFI software, http://courses.cms.caltech.edu/cs171/materials/pdfs/How_to_Dual-Boot_OSX_and_Ubuntu.pdf http://courses.cms.caltech.edu/cs171/materials/pdfs/How_to_D... offers the best guide to setting up such an environment using the Apple EFI. I've successfully followed a modified version of this guide's steps to install Ubuntu to a bootable USB drive and am very satisfied with it.
