Hmm, not sure this is making any sense to me.  40,0000,0000 is the
physical address of the *other* node's memory, ok, wait, yeah, I do get
it.

The problem is I don't know where 40,0000,0000 starts mapping into on
the other node.  Does it start mapping into 0?  In which case
40,f000,0000 is f000,0000 physical on the TXRX...?  If true, we're
hosed, because I got nothing at f000,0000.  I have memory at 0, 8, c,
and 14, but nothing at f.  So we need to figure out how those map.
Which I don't know.
