You betcha. The entire contents of files was stocked in memory at one stage.

This page details pre-1.0 development, including versions in which the
schema changed: http://subversion.tigris.org/project_status.html
In brief:
Version 1 = 0.15 to 0.27
Version 2 = 0.28 to 0.33.1
Version 3 = since 0.34

This is what I was telling you about earlier. You will need to dump with
version 0.27 or before, and load with version 0.34 or after.

Nope - schema changes were in part made to help resolve memory and
performance issues.

You will probably need to do incremental dumps - dump your repository in
50 or 100 revision chunks.

svnadmin dump repos --revision 1:100 >dumpfile-1
svnadmin dump repos --revision 101:200 >dumpfile-2
etc...

And then svnadmin load them in order.

Cheers,
Dave.
