Alright, so I upgrated to changed my xorg.conf to look like this:

        Identifier      "Mouse"
        Driver  "evdev"
        #Option "Name"                  "Logitech USB Receiver"
        Option  "Device"                "/dev/input/event4"
        Option  "Resolution"            "1000"
        #Option         "Emulate3Buttons"       "true"
        #Option         "Buttons"               "9"
        Option  "ButtonMapping"         "1 0 3 4 5 7 6 2 2"
        #Option         "ZAxisMapping"          "4 5 7 6"

And the results of thissetting now are:
* scroolling works correctly in both ways now — OK
* in 'KDM' the 8th and 9th button act as the middle one (and there is no 3rd 
button emulation) — OK
* in a KDE session though, the 8th and 9th button act as the left mouse button 
(and for some reason 3rd button emulation works)

This I find quite odd and can't figure out why. I've checked 'kcontrol' in 
case there's a KDE-specific setting somewhere, but didn't find it.
