There's "-ao volnorm" in standard MPlayer - see the mplayer manpage. It 
works, but it's not great.

If you compile mplayer with LADSPA support, you can use the 
'tap_limiter' plugin from the TAP-plugins package, see 
http://tap-plugins.sourceforge.net/ , also available as a package on at 
least Ubuntu.

If you're on Windows, try Breakaway Audio Enhancer 
(http://www.claessonedwards.com/) - it's not free, but nothing beats it 
in terms of audio quality.
