I have sometimes seen nfs problems with kboot.  You could you
try petitboot.  Get the latest 'experimental' one from here:

  http://www.kernel.org/pub/linux/kernel/people/geoff/cell/ps3-petitboot/

Another thing to try is to use a 'rescue' disk/mode to copy the files.
Most distros have them.  Fedora has a rescue mode in their installer:

  http://download.fedora.redhat.com/pub/fedora/linux/releases/10/Fedora/ppc/iso/Fedora-10-ppc-netinst.iso

Just select 'rescue' instead of 'install', or you can add
these to the boot options: 'text rescue video=720p'.

You don't need kboot/petitboot to do nfs.  To load the kernel
they just need to do tftp.
