Interesting ... but you still use your own kernel, and not the stock
Ubuntu kernel, right? That would explain how this can work...

Anyway, having a quick look at the sources, it seems to me that the
ppce500 / mpc8544ds machines in QEMU do not support any mass storage
controllor by default, so you got to specify the interface type.

For example:

 -drive if=virtio,file=...

or:

 -device virtio-scsi -drive if=none,id=c1,file=... \
 -device scsi-cd,drive=c1

Same for the graphics card, there does not seem to be support for a
default here, so try to specify it like this:

 -device VGA

or:

 -device virtio-vga
