Hi guys,

Here's a simple patch that lets the system recognize the interrupt  
controller on dual-core G5s. It's been tested on one, as well as on a  
June 2004 Power Mac G5. I'd like to know if it works on anyone's dual- 
core system, or if it breaks on any older G5 machines (Power Mac,  
iMac, or Xserve). Thanks!
