Yes, I've done it.  The key is to boot your workstation as a dataless
client off of a file server.  By dataless, I mean that root and swap are
NFS mounted from the server, /etc/fstab says to mount /usr via NFS, and
you are running a kernel that knows how to talk to local disks in addition
to NFS disks.

You can use the options "-asw" on the "generic" kernel to do this.  Tell
it to use NFS for root and swap.  Then you can mount the local disk on
/mnt and restore the /usr tapes from the remote drive onto /mnt.  (You
don't want to restore directly to /usr anyway.  Overwriting the file
/usr/etc/restore while running /usr/etc/restore is deadly.)

After it has all been restored, then you can reboot and use the real /usr.
