I had a nice message written but my macbook had a Random
Shut Down,
so here is the condensed version:
Do you see the second stage bootloader of yaboot after you
press L
for GNU/Linux? if so, try hitting tab and appending
video=ofonly to
the kernel you want to boot that appears. If those 10-15
lines are
the second stage bootloader, which it sounds like they are,
you can
add timeout= to your yaboot.conf as detailed on its guide (I
think
that it still resides on www.penguinppc.org) so that you
have more
time to add in that video=ofonly, or just add in the line
append="video=ofonly"
after your kernel configuration in the yaboot.conf.
and make sure that you have your root= correct.
finally, you could try init=/bin/sh or the like to try to
get into an
emergency shell, then blind type setup to get your ethernet
modules
installed, but that is probably not worth the effort.
Also, you might be trying to access a ramdisk without
knowing it - be
sure to turn off all initrd in yaboot, and make sure that
root= is
right (there is some strange config with initrd where root
is /dev/
ramX and there is a real_root or the like which tells where
you are
supposed to eventually end up after loading appropriate
modules).

Did you try to chroot into your finished install from the
liveCD
after it finished to make sure everything is OK? You could
also
reinstall yaboot and see if that helps, or even just run
ybin -v.

I don't know why enablecdboot and enableofboot are not
recognised -
did you make sure you put them in the beginning of the
yaboot.conf
before listing all your kernel versions?
I would say that the problem is most likely that there are
video
framebuffer problems, and since you cannot connect to the
internet or
a local subnet to ping/SSH into the computer, it is
difficult to
debug. I would try adding the video=ofonly, or some other
video=
(depending on your iMac revision, you could have an ATI
Rage, ATI
Radeon, NVidia, etc) that should be detailed in the
handbook.
hope that helps!
