How to compare two repositories?

Hi
 How would I compare two repositories to get the differences?

I am upgrading a repository from 1.1.1 to 1.4.6 and I had some problems
with a file that was checked in with a control character as a name. I
did incremental dumps (we have ~52000 revisions), fixed the problem file
and loaded into a new repository.
That seemed to work well, but I want to compare the entire revision
history of the two repositories to make sure only the changes I wanted
are there.

I tried svnlook tree for both but the order of the files is different so
that comparison failed.

Should I just do a dump of all the revisions of both repositories and do
a diff, or is there a better way? The dump file is ~7GB so that will be
a long and painful diff.

Thanks
