I had one further thought - I've seen the too-smart-for-their- britches microprocessors in USB or Firewire hubs and devices get confused and cause the host Mac to barf with a kernel panic. If the SMU/PMU reset gets you nowhere, and there are external devices connected to the G5, try removing all power from the G5, all hubs, and all devices. Unplug the power from all hubs and devices - to be really paranoid, I'd unplug the USB cables/Firewire cables too, so no device can provide power to the hub and no hub can supply power to a device. I'd try booting the G5 with no more devices attached than a keyboard and mouse. If that works, start reconnecting stuff one piece at a time and see if the problem comes back. Hope this helps.....
