Actually, I'm still seeing issues with your patch as well. Might be  
multiple independent issues that have cropped up?

In particular I'm observing that AIX on qemu-system-ppc - as reported  
by Kenneth - doesn't reach the point where it tells us the 32-bit CPU  
is incompatible. With your patch it is now possible to exit the QEMU  
process though.

Any ppc64 guests don't even seem to enter OpenBIOS at all, whether  
OpenBIOS/ppc or OpenBIOS/ppc64.

It seems there is a DSI exception when turning on the MMU in OpenBIOS  
(before any serial output occurs). Does that ring a bell with you,  
some pSeries change maybe?
