from man mkinitrd.. This leaves me to believe that yes, you /only/ need to use 
initrd if your root partition is utilizing labels..  as is default in 
redhat/fedora.

If a label is used, as in root=LABEL=rootPart the initrd will search all 
available devices for an ext2 or ext3 filesystem with the appropriate label, 
and mount that device as the root filesystem.
