What about building everything as modules and boot with an initrd that
just has your user app static linked on it and the ide + fs modules?
You can boot get your app up and going first and then go do the
probe/mount ide and then pivot_root once you get it all setup.

It needs to know lots of other stuff, ATA mode, etc.
