Well, for the record, from my limited testing it did turn out to be that
simple.  In the appropriate index directory, I ran the following commands:
  gunzip -c 20050108_0.gz | sed -e 's~^[0-9]*/./~/~' > 20050108_0
  rm 20050108_0.gz
  gzip 20050108_0

Repeated for each index file that I found there.  Then after installing
the correct version of gnutar on my Solaris box, I ran amrecover.  As far
as I can tell, all my files are now listed, and I was able to select and
extract some of them.

Looks like I'm OK anyway, but in this case it's not that important.  I'm
really still in evaluation/setup mode, so even if the tapes were totally
unusable I'm not out anything.  I've been using BRU to backup the Linux
box, which has been holding my critical data until now.  The Solaris box
is new enough that I don't have anything critical on there, but that will
be changing soon, which is why I have been looking to switch to Amanda
(don't think I can get BRU for Solaris any more).

The only thing I have left to figure out is the manual tape changer and I
think I should be ready to switch completely to Amanda.

Thanks again for the help.
