I added something here, let me know if it meets with what you expect.

I did some fixups to that (my) fs to support NFS use.  It could be you need
to fix the PS3's remote fstab file:

+++ /target/ps3/etc/fstab
@@ -1,4 +1,4 @@
-LABEL=/                 /                       ext3    defaults        1 1
+/dev/nfs                /                       rootfs  defaults        0 0

and/or remove the eth0 config file, since the startup scripts in some distros (FC)
will try to re-initialize the interface, which then disconnects the root fs.

For FC5, this is /target/ps3/etc/sysconfig/network-scripts/ifcfg-eth0

I'll add some notes regarding this to the HOWTO.  If you try these, let me know
if they work.
