You can use the netinst cd as a recovery cd by doing the following.

I forgot to mention that my iBook's CD drive is broken. :)

1. boot into the cd and at boot type recovery

Or can I boot the netboot installation images (under /boot/deb/) from the Open Firmware prompt?

2. the cd will go through the initial install process, when you get to
the part that it is setting up dhcp there should be either a 'cancell'
or 'go back' option on the bottom left. Select it
3. it should take you to a list of options one of which is recovery
mode. select that and from there you should be able to get to a bash
prompt and fix yaboot.
