It is definitely needed. The Sysptmap is tied VERY closely to the
segment table. Before, there was only one segment needed to deal with
kmem space, as 16M per segment should do for normal amigas. However, if you
add support for Z3 boards, you gotta raise that value to be able to address
the extended address space provided by those boards.

You probably have to make sure that the intermediate page tables for
the '40 are built as well when creating more segments at startup, but
that's likely already working alright.
