Heh - I just argued the toss with someone about this this morning and
lost. I thought the choices were no highmem, up to 2GB, up to 4GB and up
to 64GB but the 'up to 2GB' was a figment. However, you shouldn't use
the 64GB option unless your box has > 4GB of memory because otherwise
you're slowing your kernel for nothing.
