I have tried a couple of dump-reading utilities -- "svn-dump2dir" and "svndumptool" -- and I might be able to eventually get one to work, but I thought I'd ask this group, have any of you ran into this situation before? Is it possible to restore this dump? I don't really care about the history, the most recent version of the files would be great.

If /repositories is just a normal filesystem directory (created with "mkdir /repositories"), then attempting to use svnadmin dump on /repositories should have immediately exited with an error message like:

svnadmin: E000002: Can't open file '/repositories/format': No such file or directory

The fact that this did not happen for you, but instead a dump file was created, suggests that /repositories is not just a filesystem directory but is itself a repository (created with "svnadmin create /repositories". You can verify this by checking whether the file /repositories/format exists and by running "svn info file:///repositories"

When you say that svnadmin is unhappy with the dump file, what exactly does it do?
