There appears to be some confusion here:
    a)  floppies/ramdisk-rescue{small,tiny} are the file system images
        that are stuffed into the appropriate kernel
    b)  floppies/kernel-rescue stuffs the result of a) into kernels
        built by etc/Makefile's snap_kern target
    c)  floppies/rescue-{small,tiny}/Makefile builds the actual
        boot floppies, and those files have:
                FLOPPYSIZE=     2400
        which happens to be the size of a 1.2MB floppy :)

The INSTALL_TINY kernel has less stuff than INSTALL_SMALL, so there's
more room in it for the memory disk image file system.
Basically, the size of the kernel with a populated file system has to
compress down to fit on FLOPPYSIZE.
