Can't you make just one large mapping and lock it in 8k regions? I thought the problem with mmap was not being able to detect other processes (http://www.mail-archive.com/pgsql-general@postgresql.org/msg122301.html) compatibility issues (possibly obsolete), etc.
That mail is about replacing SysV shared memory with mmap(). Detecting other processes is a problem in that use, but that's not an issue with using mmap() to replace shared buffers.
