ReplayGain should be on the Sansa Fuze. If not, Rockbox should have support for it. http://www.rockbox.org/wiki/SansaFuze
You need to give your tracks ReplayGain meta-data, so download MediaMonkey and start it. Get your music into the program and set up volume leveling under Tools -> Options -> Volume Leveling.
Select your music and Tools -> Analyze Volume. Do not "Level Track Volume". Anyway, it'll probably need to run over night to do a whole collection. Be careful to normalize per album or something if that's what you want, unless you want your tracks all normalized to eachother for some reason.
EDIT: Foobar also has this feature! I've been using foobar for awhile but never noticed it. I typically don't bother normalizing my music.
