I have always reinstalled from cd and then done the restore. Mind you, I have never had this happen to a system partition in the wild, only during testing. Im my case I now use amanda and use amrestore, ir is it amrecover, to actually do the restore. I also have it setup to use tar so I am not dump literate. Having said all this there has to be something that can access the tape: is the device /dev/st0 really missing? by default, mt and alot of other tape utils default to /dev/tape which is symlinked to /dev/st0 on my machine.
