On i386, the vm_page tables are typically taken from the first 640k
because this is the smallest chunk of physical memory available. With
a large kernel, this might eat up last piece of memory below 16M,
leaving no space for ISA DMA bounce buffers.
[i'm going through back mail here..]
Hmm. Is there any reason why the kernel has to be resident in the
sub-16M "prime real estate" on large-memory x86 systems?
