That should be the right thing to do - I made a kernel with the unchanged extintr.c for Riccardo and it still hangs (but it still works on my S900) - must be one of the other changes that crept in recently, namely one of mine or your patches. I guess I'll diff over the entire src/sys/arch/macppc and powerpc and revert everything that's not known to do something useful.

have fun
