Ah, more involved than that - the crash on 2.4.10 seems to have left the 
spool in an odd state, like it was completely reorganizing the spool and 
got interrupted:
- $SPOOL is located in /opt/csw/var/cyrus/mail/
- Original emails were left in $SPOOL/.u/g/user/gmarler/
- A partial copy (subfolders all empty) was here:
   $SPOOL/g/user/gmarler/ (I wasn't looking here)
- Another complete copy was here:
   $SPOOL/user/gmarler/ (This is what I was looking at, but Cyrus wasn't)

- Merged everything from $SPOOL/.u/g/user/gmarler/ and 
$SPOOL/user/gmarler/ into $SPOOL/g/user/gmarler/
- Ran reconstruct -p default -rf user.gmarler
- Started cyrus and started getting these errors:
   DBERROR db4: PANIC: fatal region error detected; run recovery
- Killed off the master and cleaned up the DB4 *.db databases (except 
for db/)
- Ran reconstruct -rf user.gmarler
- Restarted master

Now everything from 1995 shows up.  Thanks for that extra tip!
