FWIW I think this image will boot with normal qemu-system-ppc too.

Wow, that's fairly old...

In my testing here, I tend to find that some versions of Linux don't 
particularly like running in -nographic mode and hangs at the point 
above. Some kernels even get upset running with a 32/15-bit display and 
must be forced to 8-bit instead :/

Can you try removing -nographic and instead try one or both of the 
following:

-g 800x600x32
-g 800x600x8

And if those don't work, try the same image again but with 
qemu-system-ppc rather than qemu-system-ppc64.


HTH,

Mark.
