The practical problem was not how much the code had to do
(except for failover.c) but instead how little of that code
was in common functions, and instead was per-motherboard.
Implementing on one motherboard while experimenting is fine but when
you go multi-board too much cut and paste is dangerous.

The first round of dual core and cache as ram code feels
like an old style adventure game:

   You have now entered a twisty maze of ifdefs.
