I've just had a look at yesterday's commit, which introduces --overlay.
great ! (Debian's Unstable is a few day behind cvs)

Since I wanted to test splashscreen, I needed to put unicode.pff
(1480KiB) + a tga image (1200KiB uncompressed)... That's why i came up
with hard disk images.

But now, with RLE'd TGA, JPEG and PNG, 2.88MiB floppy should do in most
case (I haven't tested it).

I've attached a patch for "--image-size" option. (it's GPL)

The one feature that one could miss, is the ability to mount and modify
the image, to easily customize rescue's grub.cfg, from a random
Operating system that understand fat. -- I don't need that feature.
