Attached is yet another version. In auto.c, put enable_smbus() before
your serial init, then smbus_fixup() after the serial init, so smbus can
be figuring itself out while the console is initializing. That should
take care of any problems. And yes, I have actually tested this version
first ;) You will need a DDR2 stick in slot 0 for it to work correctly,
I'll fix it up later to work with regular DDR as well (I'm sure you can
see how to fix it if you're using DDR). Again your changes (IO base and
commenting that code) will be needed.
