Gentoo Linux booting with xell-reloaded??

[ghost]

Hi, I got an Xbox 360 that should be JTAGable recently, and I was wondering if this bootloader could be used to boot external media, like a USB Flash Drive or Optical Media. I don't have a currently working disc reader at the moment, but shouldn't be an issue I hope. Would it be possible to use the PPC Gentoo install media with this bootloader, and on the hard drive?
