    Does it work?

    I have 2 keyboard/mouse/video setup as well, but I followed
    by Miguel Freitas with 2.4.23 kernel, because you have to unload
    'keybdev' USB module. Kernel-2.6.0 doesn't seem to give me that choice.
    In my XF86Config, I had to use
        Section "InputDevice"
            Identifier "USB Keyboard"
            Driver "keyboard"
            Option "Protocol" "usbev"
            Option "Device" "/dev/input/event2"
            Option "XkbRules" "xfree86"
            Option "XkbModel" "pc104"
            Option "XkbLayout" "us"
    for the USB keyboard. Note the /dev/input/event2 and "Xkb*" lines --
    they were necessary.

    Both are mentioned in XFree-Local-multi-user-HOWTO. Even though the
    HOWTO is more for Backstreet Ruby, I couldn't make head or tail of it.
