I found the --enable-diskless option, but I didn't necessarily want to
use nbgrub or pxegrub, since RPL is neither netboot nor PXE, although
possibly it could be made to work with one of those. However, I found
the stage2/diskless image -- which is usually used tacked onto a
header image to create nbgrub and pxegrub -- is exactly what I want!
Although, it's not installed by default. The open source rpld (Remote
Program Load) can load it like this:

        FILE {
                path = "/srv/tftp/diskless";
                load = 0x8200;
        };
        execute = 0x8200;

By default the diskless image fetches /boot/grub/menu.lst. Is it
possible to specify something else? Preferably something dynamic, such
as /tftpboot/grub/%s, where %s is the IP address of the booting
machine.
