Did you remember to do the above? Based on your file name I suspect not.
# file /boot/initrd*
/boot/initrd-2.6.9-34.EL.img: gzip compressed data, from Unix, max
compression
/boot/initrd-2.6.9-42.0.2.EL.img: gzip compressed data, from Unix, max
compression
My use of the -I (your -F) presumed that you did something like
gzip -dc <your-compressed-image >a-temp-file
but you could just as easily gzip -dc <image | cpio -idmvc # No -I/-F

Replace the "t" with "d" in either of the "itmcv" below and it will
extract instead of giving a TOC.
