Found a work-around on an Unbubtu list:
one must add acpi_osi=Linux to the line under "title linux" in 

Only problem, that would make this rather difficult for a newbee, is that you 
cannot do it in Mageia, since your screen is not showing; so out comes the 
Mandriva LiveCD, boot, config, mount the Mageia / or /boot partition, vi 
/boot/grub/menu.lst, save and reboot.

Only fly in the ointment, the Fn keys now work, but in reverse, v makes the 
screen brighter, and ^ make it darker.

Should this be reported as a bug ? If so, how does one do it ?

                          seulement des amis que je
                         n'ai pas encore rencontrés.
