Seems that if you have a copy of super duper you can create an image that you are able to boot from USB hard drive. It just doesn't work other wise it seems. If you noticed the apple link that USB drives aren't even supported for PPC platform either (Documentation creation was Sept. 2001).
It depends highly on the particular model and generation of Mac in question. My old G3 iBook can boot from USB, I know as I've done it before. I've never tried my G4 mini from USB, but it does boot from FireWire, of course. IIRC the main issue to have a USB bootable Mac is if it has dual USB buses or not.
I'm just glad they finally got FireWire booting working for Linux on PPC. I haven't had a chance to play with it, but it was the main thing keeping me from running Linux on my external drive with my mini.
