I suspect neither option will help. Here's the relevant excerpt from the 
mount(8) man page:

hard The program accessing a file on a NFS mounted file system will hang 
when the server crashes. The process cannot be interruprted or killed 
unless you also specify intr. When the NFS server is back online the 
program will continue undisturbed from where it was. This is probably what 
you want.

The soft entry goes on to say that soft will return a read error after a 
timeout.

I like to try and guess phrases that will appear in the document I'm 
looking for. I just typed the following into google:
"to allow" "root access" nfs

The first reference is entitled "Root Access On NFS", which appears to 
cover ground you've already seen. Perhaps other entries will help, or 
spark a realisation that you may have missed (for example, do you have to 
-SIGHUP the nfs daemon?)
