That seems wrong to me - I specifically changed the accounting so
that pieces not used from the E820 map (which can no longer be cut
off in e820.c, as that code doesn't know *where* to cut off) won't
get reported as available memory. The real question is where (for
the non-cut-off case) the two calculations differ.
