Add this to your kernel config. file:
# 1/2 RAM for the kernel - lets us have full routes.
options VM_KMEM_SIZE_SCALE="(2)"
See also /usr/include/machine/vmparam.h
Unfortunatly freebsd's kernel memory managment stuff dosn't dynamicly resize,
i'm pretty sure NetBSD's does, so you might like to take a look at that too.
