Can't install 13.04 on Powerbook 6,8 (black screen)

[flyrod]

I'm new to linux/ubuntu on a mac and I just joined several groups or mailing list things and couldn't find a more appropriate place to put this. I'm not getting very far with the install so I can't use any of the built-in bug reporting tools.

I downloaded lubuntu-13.04-desktop-powerpc.iso, burned it to a CD and tried to install on a 12" 1.5GHz powerbook (PowerBook6,8). When I boot up on the CD I get a black screen with white text that says Welcome to Lubuntu 13.04 etc. and a prompt with "live" as the default. If I select this then it says it's loading the kernel.. Elf32 kernel etc. then I get a white screen with black letters and a few lines. The last line I see says:

returning from prom_init

Then I get a blank black screen. The CD drive spins and seeks for a minute or two, then spins back down. Nothing happens if I hit enter, space bar etc.

I get this same result with various options at the first prompt: live-powerpc, live-nosplash, live-nosplash-powerpc, live video=ofonly, driverupdates, driverupdates-powerpc, check and check-powerpc.

Most of the install help documentation I've found all seems to assume that I'm getting further than this. If there is somewhere else I should be looking for info or to post this bug please let me know. Thanks.
