Interesting. My last thought was that if you are behind a PCI bridge 
then the first interrupt line may be that of the bridge device?

I've also noticed that the mac-io IDE driver also fails in its start 
method, so I'm wondering if this something more generic related to the 
IDE layer which isn't quite right in OpenBIOS?

I might try and see if I can install some kind of XCOFF gdb and take a 
look to see if I can work out from stepping through the function exactly 
which part is failing.

Well I've managed to build build binutils for Darwin here, but looks 
like the only choice with Darwin is to build their fork of gdb, and the 
development headers come with Xcode.

So given that I haven't got the tools to be able to debug this or build 
a debug kernel myself, I'm afraid that my work here is done and I'll 
have to hand the OS X baton over to someone else :(
