Since SEMMSL defaults to SEMMNS, this is guaranteed to fail if
anything else is using semaphores.

I'm not sure what you mean by this.  Did you re-define SEMMSL before
your semget, or build a new kernel with a smaller SEMMSL?

If you intend to make heavy use of semaphores, you might like to
study PR kern/12014 as well.
