    Not as such. But you can just drop a 2.4 kernel into the Immunix 7 
    system if you want to, and you don't want the kernel security features.

    The SecureID cards require the user to enter a PIN on the card's hexpad 
    keyboard. That's the kind of authentication I'm talking about. It is 
    more problematic with dongle-style tokens like iButtons and USB dongles, 
    as they (likely) will use the PC's keyboard to enter the user 
    authentication. That's problematic because it can be sniffed, unlike the 
    SecureID card's built-in keyboard.
