 Are you sure you're not getting a 'bad cramfs magic' as well? I know I
did when I tried booting a 2.4.9 cramfs-initrd with a 2.4.17 kernel.
Anyways, read fs/cramfs/README:

  <<The disadvantage is that the generated cramfs cannot always be
    shared between different kernels, not even necessarily kernels of
    the same architecture if PAGE_CACHE_SIZE is subject to change
    between kernel versions.>>
