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. Rafal
