That wouldn't work at all.  That space is not necessarily contigous at all.
It can have two freespace bitmaps right in the middle of it, depending on
the drive layout.

Furthermore, on a 10MB HPFS drive, that area is only 443 sectors, which is
not enough for a PS/2 reference partition (which not very many PS/2's
actually have - most use reference diskettes).
