I just tried `qemu-system-ppc64 -boot d -cdrom  
dvd.AIX6_OpenBeta....iso` and it hangs after:

On a real PowerMac G5 neither the above nor the ppc\bootinfo.txt  
command `boot &device;:\ppc\chrp\bootfile.exe` worked, any variations  
of it with , and/or :0 etc. lead to errors about no FDisk partition  
found or noninterposed LOAD not supported, iirc.

This is what -nographic shows me:

@Alex, any hunch what the OHCI thing is about? It doesn't appear with  
qemu-system-ppc. Some USB initialization missing in the QEMU U3  
machine init maybe?
