LinuxWatch reports that a user Hucek has successfully booted Linux on a MacIntel machine.
From the article: “The first Linux to make the jump was Gentoo since Gentoo’s Portage source-code based software distribution system makes it perhaps the most flexible and configurable of all the major Linux distributions. To boot up, Hucek had to make modifications to Intel’s open-source elilo (extensible firmware interface Linux bootloader), which replaces the BIOS on Mactels, the Linux kernel, and several drivers. With this, Hucek has been able to “boot from a USB hard disk on the [17-inch] iMac Core Duo.”
