For those with a samsung : If you REALLY want to run linux now, open your Xbox360.
Meanwhile, copy all required files (livecd, image.squash) to an usb stick or usb harddisk, and make _sure_ those file are in lowercase.
Then burn a cd, based upon the original livecd, without the squash file, but with an replacement kernel for USB (somewhere floating around also)
Then, Boot Kingkong, Connect USB drive. Press start, Insert modified linux disk.
*wait* until the penquins apears, this can take some little time.
Then, Unplug the sata cable of the samsung (at your own risk!).
You will see some exceptions, but you can go ahead with it.
Now the Bootloaderwill detect your usbdrive and procceeds with booting from that.
Note that usb support is far from stable. So don't try to install a complete gentoo on your usb disc, as it will crash.
