 kern.mbuf.nmbclusters can't be raised on i386. From sysctl(3):
 
              MBUF_NMBCLUSTERS
                      The limit on the number of mbuf clusters.  The variable
                      can only be increased, and only increased on machines
                      with direct-mapped pool pages
 
 i386 (and also sparc, FYI) have no direct-mapped pool pages AFAIK.
