In short: the amount of memory pages usable by the kernel depend on this.
Increase it if you get "out of space in kmem_map" panics (this really means:
malloc() ran out of memory where it should not have).
It override the BUFPAGES option because if you request too much pages
for buffer, then there is not enougth kmem_map entries left for the
kernel malloc.
You can increase NKMEMCLUSTERS, but I don't know what the default on
mac68k is.
