When support for relations was added the memory required increased.  I 
think that was added along with routing, I believe, which was in version 
684 or thereabouts, so that will explain what you see.

I don't use debian, but I just downloaded their package to have
a look at their mkgmap script.  If you add the option -Xmx512m after
the $JAVACMD in the line:

   exec $JAVACMD -jar /usr/share/mkgmap/mkgmap.jar "$@"

That should help.
