Thanks for the SVN revision information :)

So the main thing that changed in r828 was the handling of the bootargs 
and bootdevice properties to support multiple boot devices. This 
suggests that it could be related to the bootloader either finding a 
value it doesn't like in one of the boot properties, or the new boot 
order doesn't return correctly on invalid input.

If you load qemu with -prom-env 'auto-boot?=false', you should be able 
to manually come up with a "boot <device>" line that will invoke the AIX 
bootloader - any chance you could find out what it is? Also, what format 
is the AIX bootloader - is it an ELF executable?
