No.

You can try to boot with your own initrd?
Unpack the initrd.gz, mount it as loop, edit the script 'linuxrc' to
load the module (insmod sunrpc; insmod lockd; insmod nfs).  Copy the
modules to /lib/modules in the initrd system.  You not need all modules,
the 3 are enouth.   Unmount the loop and compress initrd to an initrd.gz
Than add
	initrd=initrd.gz
to your coLinux configuration.

Best way is, to view inito initrd.gz from your distribution, to see how
nfs boot would work.

With the initrd.gz from coLinux you would have problems, becuase it
tries to install modules in an block device, that is mounted as
/mnt/linux.  For your nfs boot you should remove the complete block for
installing modules after the echo "Mounting /", and replace it with your
lines for loading nfs modules.  $ROOTDEv is "nfs" in your case.  So, you
can create an alternate 'if'-condition for normal and the other for nfs
boot.

This are my some ideas, have never checked such boot.
