Steve:
The information on this page should get you going:
https://wiki.archlinux.org/index.php/Logitech_Marble_Mouse.
I've not tried it in Mageia yet, but I have used it successfully in Ubuntu.
The file to which you will add instructions (called 10-evdev.conf) is found in Mageia at: /usr/share/X11/xorg.conf.d/10-evdev.conf.
Essentially, all you need do (if you are right handed) is to copy and paste the parameters as they are given under the "Configuration File" heading. (Use kwrite to open the '10-evdev.conf' file; paste the Arch Linux copy at the end.) Note: If you are a lefty, you will want to make some adjustments to the parameters! Also do not forget to make a backup copy of '10-evdev.conf' before you start, so that you can put things back if the modification does not work.
Lastly, from time to time an update will come along that will return '10-evdev.conf' to its original state. In this case you will need to modify it again.
Sorry this reply has come along so much time after you posted your question, but I installed Mageia myself for the first time today.
