  For machines where the kernel address space is unrestricted increase
  VM_KMEM_SIZE_SCALE to 2, awaiting more insight from alc at . As it turns
  out, the VM apparently has problems with machines that have large holes
  in the physical address space, causing the kmem_suballoc() call in
  kmeminit() to fail with a VM_KMEM_SIZE_SCALE of 1. Using a value of 2
  allows these, namely Blade 1500 with 2GB of RAM, to boot.
