And do these OSes run on real PowerMac3,1? If so then we likely have a bug 
in USB emulation so maybe that could be fixed? In any case my patch does 
not change mac99 and this should continue to work.

Since via=pmu is what should be a real machine does it run OS X >=10.2 
already?

That doc might need some updating. It seems to be from before pegasos2 was 
added. Maybe we would be better off linking from this page to others that 
are more actively maintained such as: 
https://www.emaculation.com/doku.php/qemu 
and 
http://zero.eik.bme.hu/~balaton/qemu/amiga/

or even better updating the main docs in

https://www.qemu.org/docs/master/system/ppc/powermac.html

or somehow link these sources together.
