You're right! I checked the initrd on my SuSE 10.0 system, and it is in fact a compressed cpio archive! No wonder I had no luck trying to mount it as a loopback image :).
Another thought, though: with the old loopback initrd, all the memory used was freed after the pivot_root and the dismount. But with the initramfs mechanism putting things into rootfs, those things stay there, taking up memory, being only hidden when the real root filesystem is mounted on /. Does that make sense?
