Nope. mkinitrd is pretty smart - if you don't have mdraid/dmraid/LVM
volumes, it doesn't bother putting the modules / setup code in the
initrd. 

If you want to confirm this, you can use lsinitrd to check the contents
of an initrd yourself, e.g.:

su -c 'lsinitrd /boot/initrd-$(uname -r).img'

In short: don't bother, it won't change anything. But if you must.. 
kv=$(uname -r); mkinitrd --stuff -v -f /boot/initrd-$kv.img $kv
