I'm not sure how you intend to boot to ram with an initrd, I can think
of a few ways to do it. But I havn't ever had the chance to work on a ps3.

The first thing I would try is making a kernel with a very small
initrd/initramfs. something that has an init that just does echo "Hello
World" or some other such command just for a proof of concept for
booting off of usb. If you havn't done something like that already.

It worked the first time, It will work the second time.

None that I know of. One thought I did have was to use an initramfs
rather then an initrd. When it loads up, mount the usb stick and untar
the root filesystem.
