Again, for debugging... it would be interesting to replace this with:

LOW_PAGES = (0x100000000-__PAGE_OFFSET) >> PAGE_SHIFT_asm

... to smoke out further problems; this will take the strict definition
of "lowmem" (modulo the pci region, which someone unwisely made
dynamically adjustable... which would have been fine if initramfs could
live in highmem, which it can't yet.)
