It'd be nice if there were some functions we could call before allocating memory to let various facilities reserve some memory, but for now this seems sufficient. Previously some unfortunate systems could give up all (or at least most) of their memory to the kernel from bootmem, and then allocating command queues for packet output and the like would fail later in the boot process (which in turn would lead to crashes even later.)
