this can be viewed on two levels.  the more interesting one is the one
in which the hardware allows the software to set the size of a page for
a particular segment.  i know of cpu/mmu combinations that allow one to
select a system-wide page size from a certain set (note this differs
from software only approaches in that there is still only one page table
entry per "logical page"), but don't know of any that allow selection
of page size on a segment boundary.
