ah...that's might be all the hint that i needed:
how about this code in machdep.c 1.199 1996/08/19 line 365
/*
* Finally, allocate mbuf pool. Since mclrefcnt is an off-size
* we use the more space efficient malloc in place of kmem_alloc.
*/
mclrefcnt = (char *)malloc(nmbclusters+PAGE_SIZE/MCLBYTES,
M_MBUF, M_NOWAIT);
bzero(mclrefcnt, nmbclusters+PAGE_SIZE/MCLBYTES);
looking at /sys/sys/malloc.h, i dont see what else this might
be classified as ;(
