As I'm teacher, I'm very troubled, since I had a course to prepare and to expose in two days. But mageia2 is down.

OK stop crying.
I' using an ASUS EeePC 1012NL with NVIDIA card
precedent version was : desktop586 3.3.8-2.mga2
Well, last day I did relaxly a suggested upgrade, loading and installing ok.
3 packages wheres annonced and installed, viewable in GRUB 1.5 menu :
desktop586 3.4.24-3.mga2
netbook 3.4.24-3.mga2
tmb-laptop_3.4.24-2.mga2
But when I logically rebooted... it freezed systematicly at the same step :
