One time I got this instructions from Stuart on how to extract initrd:
cd /tmp
mkdir foo
cd foo
dd if=armedslack-current/isolinux/uinitrd-kirkwood.img  bs=64 skip=1 |
gzip -dc | cpio -div

So initrd is gzipped cpio archive, but you have to skip some data;)

By the way, I used the extracted initrd to install Armedslack on my
SD/MMC based system and there was no problem (I extracted initrd to the
MMC card and booted it as my system has to little RAM to use initrd
