1.2.3 tool managed to cope with that quite successfully.  Right now, our largest repository
(some 19,000 revisions with many files, including installation packages) is dumping.  In the
5300 range of revisions, the dump file has just passed 9GB.

Shouldn't be a problem within the limits of the OS and filesystem.  
However, I'd say why are you bothering to produce dump files?  Why not 
simply pipe the output of your dump command to a load command, e.g.

svnadmin create newrepo
svnadmin dump --incremental oldrepo | svnadmin load newrepo

You'll need space for two repos but that should be less than the space 
the dump file will take.  I included the --incremental option above 
because there's no reason to describe the full tree for every revision 
when you're doing a dump/load cycle.  You can save space with --deltas 
if you really want the dump files, but at the cost of extra CPU time.  
If you're just piping to load the CPU to calculate the delta isn't 
worth it since you're not saving the dump file.
