For 6.2 I believe the initrd is an lzma archive.[1]

As a test, on the distribution servers I have the following hashes

http://ftp.scientificlinux.org/linux/scientific/6.2/i386/os/images/pxeboot/
b3a92e0d122d437d706a877bcce03d29  initrd.img

http://ftp.scientificlinux.org/linux/scientific/6.2/x86_64/os/images/pxeboot/
e00a2019af88a21aeb7c49e3181e0c12  initrd.img

[1] upstream bug to get file to recognize lzma archives is bz#791343
