Is that still true with Mountain Lion? It is 64 bit only, so giving up say half the address space for kernel memory should not have any practical disadvantage.
Also, is that true on iOS? I would think that the better performance of say a 2G-2G split would be more than worth it there, as the hardware has, at best, 1GB or so.
