    Unfortunately the LCD/Wifi buttons seem to be managed directly by the
    hardware/BIOS. They do not generate input or ACPI events. I have no problem
    with the power button or lid generating acpi events.

    My best idea at one point was to figure out some way to reset the keyboard
    driver, but I don't know how. In theory I could modularize the whole
    serio/keyboard system etc, but then I would have no way to unload/reload the
    necessary modules without some other form of input, like over a network
    connection. I might try that anyways just as an exercise in futility.

    I tried suspend2 on a lark, but could not get it to work.. always complained
    about not being able to allocate enough pages for the image.. which was
    clearly bull.. but who knows. Google didn't turn up much.

    Thanks for your input, Jim.
