None of the stuff in "NEWCONFIG" in the i386 port is used.  That should
all probably be garbage-collected.

I was hoping to have some time to work on it in December, but the month
was much busier than I expected it to be.  I have a deadline for a
paper I need to meet in mid-January, and I'm on a holiday "vacation"
at the moment (most of my time is spent working on said paper).  I have
to edit the design document again, and send out the final revision.  I'll
try and do that this week...

(Yes, some of the recent bus.h changes were in preparation for the bus
dma stuff...)
