Maybe you did not use the right vmlinuz-chrp.initrd. Pegasos2 is a 32 bit 
machine so you need /install/powerpc/vmlinuz-chrp.initrd for it (see in 
the /install/pegasos script that is used with firmware). Even if you call 
it from qemu-system-ppc64 which includes both 32 bit and 64 bit machines 
but does not make 32 bit machines 64 bit so you still need the 32 bit OS.
