First, shmget is asking for a lot less than shmmax - why is it failing?

Check to see if things work as expected when you have shmmax and shmall
set to a shade less than 2GB and fail when they are a shade more.  If
so, it would seem there's a signed-integer-overflow bug somewhere in the
kernel's handling of shmem requests ... which would be a reportable
kernel bug.

BTW, that's at http://www.freebsd.org/cgi/query-pr.cgi?pr=130274 for anyone who wants to follow along.
