Xorg fails to recognise wheel motion on Logitech MediaPlay mouse.

Fix: 

Freedesktop.org 2389 already documents the bug but no fix has been
documented there. To fully use this mouse the above patch must be applid,
then.

    Option "Buttons"     "15"
    Option "ZAxisMapping" "14 15"
    Option "Resolution" "800

... must be added to xorg.conf

And finally,

xmodmap -e "pointer = 1 2 3 6 7 8 9 10 11 12 13 14 15 4 5"

must be added to .xsession.

A similar bug exists in XFree86 to which a patch will supplied in another
