Possibility of making a Live CD of Yellowdog?

[J Sine]

Subject says it all. Most of the PC distros have a bootable, fully functioning
evaluation version of their Linux releases (called a Live CD), but I've only 
been able to find 2 for PPC. Neither of which will boot into X on my 12" 
Powerbook. Anyone with any experience of trying/doing this? Is this even
something that an end user can accomplish? Or is it pretty much a 
maker/vendor type of endeavor?
Thanks for any help or suggestions.
