I posted where to hack the auto-tune stuff already; try it,
and let us know.  I'm convinced that you are getting the
"kmem_map too small" panic because, in fact, the kmem_map
is too small for the values you are trying to tune the
system to use, using the auto-tuning feature, since it sees
all the memory (per your posting of your dmesg).
