[Qemu-ppc] Tests with the latest ppc repo

[Programmingkid]

I used this repo for my tests:  git://github.com/agraf/qemu.git 
tags/signed-ppc-for-upstream. 

The results of the tests: 
Mac OS 10.2 install cd doesn't boot. It prints "Still waiting for root device". 
Mac OS 10.3 boots up. 
Mac OS 10.4 boots up. 

This is the command I used for testing:
qemu-system-ppc -cdrom ~/jaguariso -boot d -prom-env boot-args=-v

Jaguar is very picky about the location of the cd-rom drive. I'm guessing it 
was changed.
