One more data point : kernel loaded with quik works just fine on a 7500 with a 604e@200 CPU. So it looks like it is some particular firmware/hardware combinaison that triggers this failure mode.

The poor thing doesn't even have an integrated ethernet to start with (nor its official Apple counterpart)... Stay tuned ;-) M. -- And if you don't know where you're going, any road will take you there...
