Mageia tries to be a solid OS rather than cutting edge. Therefore they pretty much stick with nice tried and true kernel versions.
Debian Stable, Wheezy is using 3.2
If you want to use a newer kernel you will have to go to the Cauldron release or upgrade to it. You should find it is use 3.12.
Haven't looked at Mageia 4 at all. I can tell you that I ran Mageia 3 all through its Cauldron stage with very little problem and 4 is being touted on the Mageia home page for people to try it at some alpha or maybe even beta stage now. They usually do not do that until it is running fairly reliably.
I am a Debian user that admires Mageia very much.
I am not using 3.12 and I am on Sid.
Should be upto date enough for you if you get Mageia 4.
You could, however, enable the Caldron media and simply install the kernel on 3 and then disable the Cauldron media. Personally I think that would be riskier than simply installing or upgrading to 4 altogether. That is quite a jump from 3.8. Some major changes since then.
This site should give a thorough list of kernels for supported Mageia releases and Cauldron which is, of coarse supported but not yet released as stable.
I only have Mageia 3 installed on my loaner drive which only has distros that I would recommend to noobs. If I were to switch my personal OS to Mageia I would dual boot 3 and 4 and use 4 as my production OS unless it had some major breakage. I like the newer stuff too.
Stable releases really should, however, stick to a stable set of packages. This is boring but it is the most reliable way to go.
I do have both Wheezy and Squeeze on a second drive here if I succeed in breaking both Debian testing and Sid. Haven't yet this dev cycle.
