Hmm, interesting. If that change was done along with the one to
contig_initmem_init, it would have saved me well over a day of
debugging...

Anyway, I can't see where the respective freeing is done on i386, and I
still can't see how the tail part of the initial mapping is being made
use of on either 32- or 64bits.
