Look at this:

In fact oldworld machines have buggy openfirmware but linux detects  
them by looking if there is an interrupt-controller.
Better way should to look at the openprom model property.

We have chosen to emulate an oldworld machine first, because hardware  
is simpler, but we are using openbios which is a v3 openfirmware. So  
we have an oldworld hardware with v3 openfirmware. To be able to boot  
we add in the openbios device tree some "AAPL," properties linux uses  
on oldworld machines.
