well, that's a good one

hmm, i have no experiences with yaboot at all.
but wouldn't it be possible to use yaboot to boot into grub to put into 
whatever (linux) you want? (kind of "chainloader")

initrd will not help you with your bootloader (but with the drivers 
needed to bring up your system)
anyhow, you will have to tell your bootloader to tell the kernel to use 
the initrd file; search the net for "yaboot+initrd" and you should get 
some hints on how to do it.
finally, afaiu you could use the yaboot prompt to try out things before 
locking yourself out of the machine permanently (but you probably know that)
