initrd-tool can do either ext2 or cramfs, but not really initramfs, altough i believe you can override it with the right invocation to cpio used with the right option of initrd-tools. it defaults to ext2 on 2.4 kernels and cramfs on 2.6 ones, i believe. initramfs-tools and yaird default to initramfs format, but could probably generate cramfs or ext2 just as well.
