Matt,
I've had ISA initially working on FreeBSD/ppc with kernel console over 
sio in particular, when doing a port to MPC750 CompactPCI board. I don't 
have my changes at hand as I had to return the (loaner) equipment and 
kind of dropped the activities around it. But from what I remember it 
wasn't very hard to get sio in kernel working - there was some VIA 
PCI-ISA bridge chip with driver already supported for i386, so after 
gluing it to powerpc kernel and setting proper address ranges in 
device.hints for sio it worked.

I could dig in my archives for those changes sometime next week if 
you're interested.
