There is a table in one of several address spaces. The intel MP code we
have finds the table, checks it and uses the data within. See the intel
multiprocessing spec v1.4.

You need to do it at boot as we may blow away some places it can hide, you
also need to understand some boards have a table listing two CPU's but only
one CPU

With the AVL tree back in an 8Mb 386 is perfectly happy doing everything I've
thrown at it.
