When using NFS roots you haven't seen any hung clients?  I was getting a
lot of those, got rid of a lot of the hangs by using the /dev/urandom
workaround, but still got a few after that, attributed to a long-lived
Linux NFS client kernel bug.  See these threads:

    05 May 2004:  xenolinux /dev/random
    12 May 2004:  Xen hangs with NFS root under high loads

I'm sure 1.3 fixes the first, but what about the second?
