Your friend in such situations is often the file command:

[chris at chris ~] file /boot/initrd-2.6.16-1.2122_FC5.img
/boot/initrd-2.6.16-1.2122_FC5.img: gzip compressed data, from Unix, 
last modified: Wed May 31 22:38:04 2006, max compression
[chris at chris ~]$ gunzip </boot/initrd-2.6.16-1.2122_FC5.img 
 >initrd-2.6.16-1.2122_FC5.uncompressed.img
[chris at chris ~]$ file initrd-2.6.16-1.2122_FC5.uncompressed.img
initrd-2.6.16-1.2122_FC5.uncompressed.img: ASCII cpio archive (SVR4 with 
no CRC)
