How about copying the stuff to the end of available memory.  During
startup in setup_arch() the kernel decides what it needs and what not.
All the required stuff will be copied down just after _end.  The
memory range from behind the last junk to the end of memory is then
returned and initialized as normal.

This makes it necessary that the kernel makes it's decissions very
early.  I think we can live with that.
