Under Memory:
"The 32-bit server kernel supports up to 64 GB of memory; the desktop
kernel, a mere 4 GB (CONFIG_HIGHMEM64G=y, CONFIG_HIGHMEM4G=y)."

If you want to compile your own kernel image, just set HIGHMEM to 64G
and you'd see it all, or just figure out how to install the server
kernel image.
