PowerPC interrupt setup

I am stuck with porting the Fiasco microkernel to PowerPC. I can't  
find any clear documentation about how to setup a interrupt  
description table. So, these are my questions:

1. How is an interrupt descriptor formed on PowerPC? How does it look?
2. Where (in memory) do I need to store these descriptors?

The IBM PowerPC Programming Manual gives me a good overview but no  
information on how to implement it. Can someone please point me to  
some meaningful documentation?
