Thats exactly the reason.  A good explanation of why can be found at:

I really wouldn't worry about it.  Not many people use Netscape 4, and even
less will have JavaScript turned off.

Pretty simple.  Make your front page up with a message explaining how to
turn JavaScript on, and then use JS to redirect immediately to the proper
front page.  Eg:

    <head>

    <script language="javascript">

    window.location = '/index2.html';

    </script>

    </head>

    <body>

    <p>Blah blah how to turn JavaScript back on blah blah</p>

    </body>

This way, a use with JS turned off will see the message, and a user with it
turned on will be immeditately redirected before they see the message.
