GRUB uses this call but it doesn't know how to pass this information to
the Linux kernel.
I believe that "--no-mem-option" should become default. "--mem-option"
should be introduced instead for the kernels that still need it.
A kernel that can boot from a floppy without relying on anything but a
16-bit BIOS can and should be trusted with the hardware detection.
