Replying to my own post again:

Success!

It seems the problem was the old version of rrdtool that was installed 
long ago. I deleted that (and everything that depended on it) and 
installed the new version from the opennms yum repository. Opennms 
startup still puked because it didn't like the libjrrd.so in 
/usr/local/lib so I pointed rrd-configuration.properties to the one in 
/usr/lib64 and I can now see my old data. New data is being written as well.

Now it's on to migrating all this to new hardware...

       ...jgm
