Presumably the issue is most likely FCode on the card being run to
initialise failing because the OBP is missing some feature or other?
Is there any way to determine what is failing?

I wonder what the chances of finding a workaround by dumping all the
OF properties on the same card in a sun4c and sun4m box and seeing if
there was any additional setup the OS could do to fill in the gaps?
