Lower VM_MIN_KERNEL_ADDRESS by 128MB on non-SRMMU systems (sun4/4c/4e) as well,
in order to give these systems a more reasonable amount of kva, yet still
providing .75GB to userland processes.
Although there is no dependency upon a recent boot loader on non-SRMMU systems,
SMALL_KERNEL will nevertheless stick to the legacy kvm layout, for the time
being.
