I don't believe that you can specify an initrd at the boot: prompt.
Yaboot will pass kernel arguments such as "root=...", but "initrd=..."
is not a kernel argument.
Looks like you have to recover the system some other way.
It would be nice if yaboot allowed the user to specify an initrd on
the command line.
