I don't remember the exact filename limits for Joliet/Rock Ridge, but
something like this:

`find /base/path/ -name "??????????..????????????*" -print`

Should find them all.

The catch is, you have to replace the ?????? part with the same number
of question marks as the longest allowed filename in Joliet or RR.  

("?" matches on exactly one character -- no more, no less -- including
spaces/digits/symbols/etc.  "*" matches on any number of any character,
including a null character.  So in English this command line reads like
"find every file under the path /base/path/ that has at least [number of
?'s] characters in it, and either ends there or has anything else after
it.")

There might be a shortcut syntax for find, I'm just not sure...something
like `find /base/path/ -name "?{0,255}*" -print`, maybe...you'll have to
play around to find something that works, but I'll be curious to know
what you find if you do find a shortcut...
