  Log:
  Increase NKPT from 17 to 30.  This fixes the 4GB ram boot panic on both
  -current and RELENG_4 with GENERIC.
  
  NKPT is the number of initial bootstrap page table pages we create for
  the kernel during startup. Once VM is up, we resize it as needed, but
  with 4G ram, the size of the vm_page_t structures was pushing it over
  the limit.  The fact that trimmed down kernels boot on 4G ram machines
  suggests that we were pretty close to the edge.
  
  The "30" is arbitary, but smaller than the 'nkpt' variable on all
  machines that I checked.
