I believe is orthogonal to an initramfs. The initramfs lives in /boot, and if the boot loader (LILO, GRUB, GRUB2) cannot mount /boot, then there is no initramfs. That's why GRUB2 is so damn big (it implements LVM among other things, or at least the minimal to mount partitions read only), and why some people are pushing for "Linux to boot Linux", sometimes called /firstboot. GRUB2 can mount my /boot inside LVM. Perhaps with UEFI all this will become irrelevant.
