    Dumb question applicable to 9x% of computers: how do you secure the suspend
    switch and OFF switch, not to mention the power plug or the battery?

    As to security many portables have a bios password and no other passwords
    thereafter for the user account. The abort feature events could be enabled
    via swsusp proc entry mainly for (desktop) security. Also, then you ought
    to think about securing suspend events (don't swsusp the webserver please)!

    In practice, when suspending, in many cases one would like to abort. Suspend
    should be abortable by ESC and post 1.0: the lid switch and/or suspend switch.
    If you think about it it makes sense to abort suspend instead of having
    to wait 15-40 seconds and reenter the bios password and wait another 10-30
    seconds. (assuming 2.4 speeds)

    The way I would use S3/S4 is reboot only for a new kernel, and really use the
    machine portably much more. S3 would be used for short suspends and S4 for
    longer suspends.

    In short, this is an _important_ feature _as_ much as S3 and S4.
