You can do this:

        # dd if=partboot.img of=fs.gz bs=1k skip=X
        # gunzip fs.gz
        # mount -o loop fs /mnt/tmp
        [edit away, and gzip up again, etc.]

X is the offset of the init ram disk.  Linux will say this when the
bootdisk boots... "found initrd at offset X", or something similar.

Just a matter of writing a shell script, and playing with /etc/inittab,
or whatever.

Good luck :)
