Yaboot is the powerpc boot screen version (like grub2 in the amd64 and
i386 flavors). When you get to a screen that say boot:  You can hit
enter of type Linux to get the bootup started.  If you need to give
kernel commands you would type " live video=radeonfb:1024x786-32@60"
That would get you past a radeon kernel bug into a clean working
desktop. On my PowerBook G4 I need that when I first start to get a
live desktop because I have radeon graphics.
Now the recursive bug is a kernel-sound problem and requires a kernel
command like "snd-powermac.blacklist=yes" also.

Now i always use USB flash drives for my installs and i have to get
into open firmware to get the USB recognized.
When i start the PB G4
1) Iand have the USB plugged in
2) I hold down Option+Apple Keys and o+f
3) then i type "boot usb0/@1:2,\\yaboot" not with the parenthesis
4) The kernel start and ram drive
5) I now come to the yaboot install screen and see boot: and information above
6) I type  "live video=radeonfb:1024x786-32@60 snd-powermac.blacklist=yes
7) the radeon part is a graphic issue the snd-powermac stops the recursive bug
8) I then get a clean live desktop and make my hardware installs then.

After the install finishes and if I typed everything correctly I do no
need kernel commands to get to the fresh install. We are aware the
graphics and sound issue are kernel regressions as the 12.04 powerpc
installs without a hitch with the old kernel.
Wow I typed more than I intended.  I would recommend you spend some
time reading the PowerPC facts good information there.
