I don't expect this to work with OpenBIOS on QEMU as I think we don't have 
a USB driver for storage devices. I've only ported a hid driver for 
keyboard on OHCI so unless there was a change in this that is all OpenBIOS 
would see from USB and should not find USB disks.

Also G5 Mac emulation in QEMU is probably not that good as G4 is now so 64 
bit version may have more problems than 32 bit ppc.
