try


Linux/PPC load: root=/dev/nfs rw nfsroot=A.B.C.D:/NFSROOT nfsaddrs=IP_OF_TARGET:IP_OF_NFSROOT_SERVER:IP_OF_DEFAULT_GATEWAY:NETMASK

so I use

Linux/PPC load: root=/dev/nfs rw nfsroot=192.168.1.2:/ppc nfsaddrs=192.168.1.22:192.168.1.2:192.168.1.8:255.255.255.0

how should it ever find /sbin/init if it never mounts the nfs-root filesystem ?
and from the kernel messages you sent it did not mount any root filesystem .
