For the arm x86 thing yould should maybe start a new thread ...
FWIW, in the meantime there has been pretty much going on regarding the Mageia ARM port.
We got two ARM build nodes added to the Mageia buildsystem:
[council] New ARM server
[sysadmin-discuss] welcome to our new ARM server
[sysadmin-discuss] armagnac is now live
IIRC, armv5tl basesystem and its buildrequires, including Qt4, Gtk2/Gtk3 have already been rebuilt in cauldron.
The ARM port has also been added as a feature targeting Mageia 6: https://wiki.mageia.org/en/Feature:ARM_Port
See also https://wiki.mageia.org/en/Installing_M ... OS_devices which has been updated often in the meantime.
