I guess you need to have the HDD driver built into the kernel, or
in the initrd.

See the kernel source file Documentation/kernel-parameters.txt
I think just this is enough:

  root=/dev/nfs ip=any

Seems to be an NFS config problem on the server.  Check the config and
log files.

None of your problems seem to be PS3 specific.  You can get help from
