Check your root filesystem.

Which of the files "/bin/sh", "/sbin/init", "/etc/init" and "/bin/init"
do exist, and which don't?

In this filesystem only "/bin/sh" exists, while the ohers don't. This
explains the exit codes.

I have put a set of more complete ramdisk images (based on  the  SELF
RPM  from our ELDK 2.0 distribution) for download from or FTP server;
see ftp://ftp.denx.de/pub/LinuxPPC/usr/src/SELF/images/

But there is nothing wrong with the mini-2048kB-ramdiskimage.gz  file
- it still works fine here.

I think you should try to boot the system with root  filesystem  over
NFS  instead - it is much easier to debug (use a network sniffer like
ethereal to check the traffic on the wire).

Best regards,

Wolfgang Denk
