As I know there are other Mageia users that use the rEFInd boot manager, I've submitted my patches to add support for this in drakboot (the boot configuration GUI used in the installer and MCC) at https://bugs.mageia.org/show_bug.cgi?id=15153. This just provides an easy way of creating and modifying the refind_linux.conf file in /boot to configure the boot menu entries and options that are accessible via the F2 key in rEFInd. Note that the same configuration applies to all kernel versions found in /boot (which will be presented as separate icons on the rEFInd boot screen) - this just lets you set up normal/noframebuffer/failsafe entries and add any necessary kernel boot options.
I don't hold out much hope that these patches will be accepted (or even noticed) by the Mageia developers, but it's not hard to apply them yourself if you want to.
