This was my first try using yaboot 1.3.17. So that version probably
never worked on my iBook.

The CD and drive are fine. The problem is yaboot 1.3.17. Rather than
create a new sid netinst iso with an older yaboot, I decided to just use
the yaboot 1.3.16 from the latest jessie netinst iso to springboard into
the sid installer. In case anyone is interested, the procedure was:
1. download jessie powerpc netinst iso[1] and dd it to a USB stick
2. boot into open firmware
3. start yaboot 1.3.16 from jessie usb stick
boot usb0/disk@1:2,\install\yaboot
4. from yaboot 1.3.16, switch to sid netinst (CD-ROM)
conf device=cd file=/install/yaboot.conf
5. run installer
install32
This allowed me to install sid on my iBook/G4. I'll see if I can bisect
where yaboot broke on my iBook.

Thanks! I'll start getting this setup. I'll document my procedure in
case anyone else is interested.
