Chrome just calls xdg-open. Have a read through the xdg-open source  
code (it's a quite readable bash script). If you've got Gnome, KDE, or  
XFCE running, it will use the corresponding openers, so you should  
just set the default application using that DE's settings widget.  
Otherwise, it's trying $BROWSER, then firefox, then a few other  
fallbacks, so just set $BROWSER to something that knows how to choose  
the right program for its argument and rock on.
