Shouldn't matter.

You can't do 100MHz system bus speed in an E4000/E5000 - only the E3x00 
and E4500/5500.  They'll just run at 83MHz.

Probably.  I've got a few extras (and some SBUS soc+ cards).

Have you tried reflashing the system first?  It's possible that the 
problem has a too-old OBP/POST version or something.  One of the notes 
in the Sun system handbook says this:
"OBP >=3.2v14 is required when 83MHz and 100MHz boards are mixed."

So, I'd recommend flashing the system with the old I/O boar in the 
machine, and then try the soc+ board again.
