Hi,

i tested your image and it boots on my G5.
But you have a different G5 than I.
I have PowerMac 11,2 but you have PowerMac7,3.
And i checked the settings, it looks also good.

How good are you at NetBSD kernel programming ?
You could try to debug it with printf, it's probably some minor issue at 
system initialization and could be easily fixed, maybe.

I had similar issues with my G5 at the beginning, MMU was not properly 
initialized and some other issues.

regards
