 This still happens on netbsd-6, but HEAD sun2 kernels works.
 
 Pulling sys/kern/subr_kmem.c rev 1.46:
  http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/kern/subr_kmem.c#rev1.46
 to netbsd-6 also fixes this panic.
 
 Does it also include some implicit bug fixes,
 not only improvements for >4KB allocations?
 Or "decrease overall memory" is mandatory
 for poor tier II ports?
