So the bug most certainly originates upstream. The bootscript used for PowerMacs
is sourced from this template:

So, either the template is wrong or the part of GRUB which processes the template.

If just removing the extra colon fixes the problem *and* also does not break the
boot using a CD-ROM (which currently works so it should be tested it still does
with the change), we should fix the bug upstream.

I'm not sure I have booted the iBook G4 with the unpatched Yaboot so I don't know
but it's not relevant now anyway.
