The initrd file is just a gzipped ext2 filesystem image, so you need to
uncompress it into a temporary file and then mount that file using loopback:

zcat /boot/initrd-`uname -r`.img >/tmp/fs
mkdir /mnt/initrd
mount -r -t ext2 -o loop /tmp/fs /mnt/initrd

Then you can look under /mnt/initrd to see the contents of the initial ramdisk.
