Okay, I've had the same problem and "misuse" Lua to make a redirect possible based on the browser language.

# Use Lua for HTTP redirect so the site works

    rewrite_by_lua '
        for lang in (ngx.var.http_accept_language .. ","):gmatch("([^,]*),") do
            if string.sub(lang, 0, 2) == "en" then
                ngx.redirect("/en/index.html")
            end
            if string.sub(lang, 0, 2) == "nl" then
                ngx.redirect("/nl/index.html")
            end
            if string.sub(lang, 0, 2) == "de" then
                ngx.redirect("/de/index.html")
            end
        end
        ngx.redirect("/en/index.html")
    ';
}

Note: NGINx needs to have liblua compiled to it. For Debian/Ubuntu:

apt-get install nginx-extras
