Not really.  QGIS, I suppose, but getting QGIS running on your system might
be too much work.  If you're lucky, perhaps there's a binary packge for it.

Oh, yeah, ESRI ArcExplorer should work, too.  I can't recall if they've still
got a Java version --- I ran it even on my BSD systems for a while.  I still
have a copy of ArcExplorer 9.1 that's the java version.  Looks like they still
do have it and are up to version 9.3:

If push comes to shove, you might be able to run their Windows version under 
Wine.
