KDE scrollbars react to the wrong mouse buttons

I have an Microsoft Explorer Trackball (5 buttons + scroll), but
honestly up to now, I never bothered to try to get the other 2 buttons
to work.  I also normally disable the trackpad, because it annoys me!

I did just get it working with all 5 buttons. I don't know if that fits
your definition of 'many', but it is more than 3! :-)

Section "InputDevice"
    Identifier "Mouse0"
    Driver "mouse"
    Option "Protocol" "ExplorerPS/2"
    Option "Device" "/dev/input/mice"
    Option "Buttons" "7"
    Option "ZAxisMapping" "6 7"
EndSection

I also added "pointer = 1 2 3 6 7 4 5" to ~/.Xmodmap

The only 'problem' with this is that the trackpad has 4 buttons in a
N-S-E-W layout. With this config, the buttons are reported as

       1
    1     3
       6

So the W and E buttons are what you would expect, but the 'N' and 'S'
buttons are basically useless. But as I said, I normally disable the
trackpad anyway.

I think you should be able to get this to work with your trackball, at
least for most of the buttons. If you *must* use the evdev protocol to
get all the buttons to work, then you will have to wait for
XInputHotplug to become a reality.

I never had any need to fiddle with this, so I am not really sure. I
guess one mouse would move uncomfortably fast or slow, and you would
have to find a compromise between them. I don't think this applies to
trackpads.
